SUMMARY:Is My Subgroup Normal? How Math Communities Differand Why it Matters (Sinclair\, Google)
DESCRIPTION:Mathematics isnt done in a void: its done by groups of people. Those groups have\ndifferent norms and values\, which affect both who wants to engage in math and the mathematics itself\nbeing done. When thinking about diversity and inclusion\, explicitly examining norms within our\ncommunities can get us a long way. Through a Thomas J Watson Fellowship\, I had the opportunity\nto experience mathematics competitions communities in Brazil\, Argentina\, Senegal\, Singapore and\nEngland. Come hear about the differences I found within those communities\, and how Ive continued\nto connect those learnings to technical communities back in the United States.

SUMMARY:A Conformal Mapping Approach to Shape Optimization Problems. (Kao\, CMC)
DESCRIPTION:Abstract: In this talk\, a conformal mapping approach to shape optimization problems on planar domains will be discussed. In particular\, spectral methods based on conformal mappings are proposed to solve Steklov eigenvalues and their related shape optimization problems in two dimensions. To apply spectral methods\, we first reformulate the Steklov eigenvalue problem in the complex domain via conformal mappings. The eigenfunctions are expanded in Fourier series so the discretization leads to an eigenvalue problem for coefficients of Fourier series. For shape optimization problems\, we use gradient ascent approaches to find optimal domains that maximize objective functions involving Steklov eigenvalues.

SUMMARY:A General Bayesian Discrete Time Survival Model (King\, CPP)
DESCRIPTION:Abstract: “We present a general Bayesian statistical model for discrete time\, discrete state space stochastic processes. Applications include the modeling of recurrent and episodic disease processes\, such as episodes of illicit drug use\, as well as social processes such as educational enrollment and employment. We also present Markov chain Monte Carlo inference algorithms for our model\, along with a freely available software package called “brea” which implements these methods in the R programming language.”

SUMMARY:On the interplay of functional analysis and operator theory (Puig de Dios\, UCR)
DESCRIPTION:Abstract: We overview some basic and striking facts concerning the theory of hypercyclic operators (considered to be born in 1982): \n\n1. Hypercyclicity is a purely infinite-dimensional phenomenon: no finite dimensional space supports any hypercyclic operator;\n\n2. It is not easy at all to determine whether a linear operator is hypercyclic. However\, the set of hypercyclic operators is dense for the Strong Operator Topology in the algebra of linear and bounded operators;\n\n\n3. Hypercyclicity is far from being an exotic phenomenon: any infinite-dimensional separable Frechet space supports a hypercyclic operator.

SUMMARY:Reasoning about Liability of Intelligent Agents ( Naumov\, CMC)
DESCRIPTION:Abstract: As intelligent agents assume larger role in our daily lives\, reasoning by humans about liability of such agents as well as reasoning by the intelligent agents themselves about liability becomes more important.  The existing laws\, written with humans in mind\, will eventually need to be re-interpreted in terms of their applicability in a hybrid environment that consists of humans and intelligent agents.  In some cases\, new laws will need to be written to redefine liability in the context involving intelligent agents. As a first step in this direction\, we need to have a formal definition of liability that can be applied to intelligent agents and logical rules that the machines can use to reason about their own and human liability. In this talk I will discuss several of my recent works on formal logical systems for reasoning about liability.

SUMMARY:Accidental Mathematics (Matt Stamps\, Yale-NUs College)
DESCRIPTION:Abstract:  Growing up\, I always loved learning about world-changing scientific breakthroughs that were discovered by accident.  Penicillin\, artificial sweeteners\, X-rays\, and synthetic dyes are just a few of the discoveries that were stumbled upon by scientists who had other goals in mind.  More recently\, I have come to wonder why anecdotes about accidental discoveries in mathematics are not as commonplace.  Is it a fundamental difference in they way mathematicians and natural scientists view their work?  Are such stories too contrary to the popular perception that success in mathematics is reserved for the genius of a select few?  Whatever the reason\, I argue that mathematics happens accidentally all the time.  In this talk\, I will describe two accidental discoveries from my own work involving Penrose tilings\, circle packings\, chordal graphs\, lecture hall partitions\, lattice polytopes\, and polynomial rings.

SUMMARY:Pull Out All The Stops: Textual Analysis via Punctuation Sequences (Mason Porter\, UCLA)
DESCRIPTION:Abstract: Whether enjoying the lucid prose of a favorite author or\nslogging through some other writer’s cumbersome\, heavy-set prattle (full\nof parentheses\, em-dashes\, compound adjectives\, and Oxford commas)\,\nreaders will notice stylistic signatures not only in word choice and\ngrammar\, but also in punctuation itself. Indeed\, visual sequences of\npunctuation from different authors produce marvelously different (and\nvisually striking) sequences. Punctuation is a largely overlooked\nstylistic feature in “stylometry”\, the quantitative analysis of written\ntext. In this paper\, we examine punctuation sequences in a corpus of\nliterary documents and ask the following questions: Are the properties of\nsuch sequences a distinctive feature of different authors? Is it possible\nto distinguish literary genres based on their punctuation sequences? Do\nthe punctuation styles of authors evolve over time? Are we on to something\ninteresting in trying to do stylometry without words\, or are we full of\nsound and fury (signifying nothing)? \nFor more information\, see our recent preprint (joint work with Alexandra\nDarmon\, Marya Bazzi\, and Sam Howison):\nhttps://osf.io/preprints/socarxiv/2rzsg

SUMMARY:Personal Perspectives on m-ary Partitions (James Sellers\, Penn State)
DESCRIPTION:Abstract:  A great deal of my research journey has involved the study of m-ary partitions.  These are integer partitions wherein each part must be a power of a fixed integer m > 1.  Beginning in the late 1960s\, numerous mathematicians (including Churchhouse\, Andrews\, Gupta\, and Rodseth) studied divisibility properties of m-ary partitions.  In this talk\, I will discuss work I completed with Rodseth which generalizes the results of Andrews and Gupta from the 1970s.  Time permitting\, I will then discuss several problems related to m-ary partitions\, including my work with Neil Sloane on non-squashing stacks of boxes\, an application of m-ary partitions to objects known as “unique path partitions” (which are motivated from representation theory of the symmetric group)\, as well as very recent work with George Andrews and Aviezri Fraenkel on the characterization of the number of m-ary partitions of n modulo m.  Throughout the talk\, I will attempt to highlight various aspects of the research related to symbolic computation.  The talk will be self-contained and geared for a general mathematical audience.

SUMMARY:Cracking the Code: Predicting Properties of Material Fracture Networks using Machine Learning (Allon Percus\, CGU)
DESCRIPTION:Understanding how fluid flows through heterogeneous materials\, and how it can make these materials fail\, are among the hardest challenges in materials science.  Experiments and simulations show that flow through subsurface rock is mostly limited to a small subnetwork\, or backbone\, of fractures.  Identifying this backbone would allow for a large speedup in flow and transport simulations\, but the process of identifying it can itself be computationally intensive.  I will discuss a machine learning approach\, developed in a CGU Math Clinic project with Los Alamos National Laboratory\, that rapidly finds relevant subnetworks based on graph structure and training data from simulations.  Time permitting\, I will also describe a method that uses graph convolutional neural networks to predict\, with high accuracy\, how fractures grow in brittle materials.  This provides an automated approach for learning how the fractures can radiate through the material\, and ultimately cause it to fail.

SUMMARY:Algebraic and Polyhedral Perspectives on Combinatorial Neural Codes (Robert Davis\, Harvey Mudd)
DESCRIPTION:In the 1970s\, James O’Keefe and his team observed that certain neurons in the brain\, called place cells\, spike in their firing rates when the animal is in a particular physical location within its arena. If a place cell is thought of as either “active” or “silent\,” then one may represent the co-firing patterns of place cells by a combinatorial neural code: a set of 0/1 vectors whose coordinates represent that status of distinct place cells. From the code\, we can try to reconstruct a geometric picture of the neural activity by sketching a disjoint union of simple closed curves in the plane. Ideally\, each curve corresponds to a unique place cell and the interiors of the curves are convex. However\, this is not always possible\, and identifying criteria which makes this possible is a difficult problem. \nIn this talk\, we will discuss approaches to the problem of representing combinatorial neural codes using convex sets. We will see how turning the codewords into polynomials can reveal hidden information about the code\, and how this naturally leads to examining properties of related polyhedra. In particular\, we will present progress on using polyhedra to identify representability of a code with circles in the plane.

SUMMARY:Mathematics: Pure\, Applied\, A Liberal Art ( Al Erisman\, Seattle Pacific University)
DESCRIPTION:From the view of a pure mathematician\, those working in pure mathematics produce pure knowledge. Whether used or not\, it has a great elegance and value in and of itself. Those in applied mathematics simply pick up what has been done and use it in designing or building things. Number theory is often used to illustrate this\, where work done decades ago in pure mathematics is now central to encryption. \nHowever\, the relationship between pure and applied mathematics is a bit more complicated. New insights drawn from applications have been at the root of interesting new areas and questions in pure mathematics. Fourier analysis\, sparse matrix computation\, and graph theory all demonstrate this. \nSome have argued that\, whether pure or applied\, mathematics is not really needed by the average person. Alfred North Whitehead\, a Harvard mathematician and philosopher\, once stated\, “ideas [from mathematics] are of highly specialized application\, and rarely influence thought.” In other words\, mathematics is a specialized skill\, but not a liberal art. \nUsing examples from n-dimensional linear algebra\, I will show why I believe the areas of pure and applied mathematics are deeply tied\, and that this field does indeed influence thought in areas like understanding relationships and political discourse.

SUMMARY:The kissing number and related problems (Oleg Musin\, University of Texas Rio Grande Valley)
DESCRIPTION:Abstract: \nThe kissing number problem asks for the maximal number k(n) of equal size nonoverlapping spheres in n-dimensional space that can touch another sphere of the same size. This problem in dimension three was the subject of a famous discussion between Isaac Newton and David Gregory in 1694. In three dimensions the problem was finally solved only in 1953 by Schutte and van der Waerden. In this talk we are going to give an overview of this problem and to present our solution of a long-standing problem about the kissing number in four dimensions. We are also going to discuss Tammes’ problem and other optimal sphere packings problems.

SUMMARY:Convolutional Dictionary Learning for Tomographic Reconstruction (Cristina Garcia-Cardona\, LANL)
DESCRIPTION:Convolutional sparse representation is an efficient tool for computing sparse representations for entire signals in terms of sums of a set of convolutions with dictionary filters. Unlike representations that are based on overlapping image patches\, the convolutional representation optimizes over the entire image\, yielding representations that are very sparse both spatially and across the filters. This technique has been successfully applied to natural images\, video and speech in tasks as diverse as denoising\, classification or superresolution. In this work\, we develop a convolutional dictionary learning framework for tomographic reconstruction. We apply the technique to simulated parallel beam tomography data and show that its performance is comparable to the state-of-the-art reconstruction techniques.

SUMMARY:Coupled Mechanochemical Multiscale Model to Study the Growth Regulation and Morphogenesis during Tissue Development (Weitao Chen\, UCR)
DESCRIPTION:Growth regulation and pattern formation are two main problems in developmental biol-\nogy. How cells know when to stop growing at certain tissue size with specic shape is an important\nquestion in both developmental biology and regenerative medicine\, and it is still an unsolved mystery\nin many systems. During the growth\, tissues and organs always exhibit self-government to some\nextent. Cells stop proliferation precisely when the intended size of the tissue or organ is achieved.\nMeanwhile\, dierential cell shapes in space are integrated to give rise to well-organized overall struc-\nture. Uncontrolled growth of the cells in tissues or organs will lead to abnormal development or\nfatal diseases such as cancer. Therefore\, developing an extensible predictive mathematical model\nfor exploring the mechanisms involved in the tissue development is signicant for understanding\nthe fundamental principles in developmental biology\, with a broad range of applications from tissue\nengineering to biomanufacturing and biotech industry. Experimental data suggests that mechanical\nproperties of cells and chemical signals in both intracellular and extracellular domains play critical\nroles in size control and shape formation. Here we develop a multiscale\, mechochemical coupled\nmodel of tissue growth control. This rst-of-class modeling approach provides sub-cellular details\nto both mechanical properties and chemical signaling during tissue growth. This model is applied\nto test competing hypotheses in the eld to resolve the highly debated question of how tissues reach\ntheir nal size\, as well as how the tissue shape is determined simultaneously.

SUMMARY:The Legacy of Rudolph Kalman (Andrew Stuart\, Caltech)
DESCRIPTION:Abstract: In 1960 Rudolph Kalman published what is arguably the first paper to develop a systematic\, principled approach to the use of data to improve the predictive capability of mathematical models. As our ability to gather data grows at an enormous rate\,  the importance of this work continues to grow too. The lecture will describe this paper\, and developments that have stemmed from it\, revolutionizing fields such space-craft control\, weather prediction\, oceanography\, oil recovery\, medical imaging and artificial intelligence. Some mathematical details will be also provided\, but limited to simple concepts such as optimization and iteration; the  talk is designed to be broadly accessible to anyone with an  interest in quantitative science.

SUMMARY:Saving Bats from Fungal Diseases with Linear Algebra (Nina Fefferman\, U of Tennessee-Knoxville)
DESCRIPTION:Abstract: Bats in North America have been dying off due to the invasion of a fungal disease (White Nose Syndrome). In this talk\, I’ll present a very simple linear algebraic model to predict the magnitude of the die-offs. By comparing these models to some data about actual bat survival\, my collaborator and I also hypothesized that the disease might be causing rapid evolution in the bat populations and this could give some populations better hope of surviving. I’ll go through these models and show how the predictions they make are different from models that don’t include bat evolution. I’ll also talk a little about some of the intervention strategies that have been proposed to help bat populations survive\, and use these models to show how some of them might accidentally hurt rather than help\, if we don’t figure out whether the main impacts of disease are evolutionary or immunological first.

SUMMARY:Isometric Circle Actions (Catherline Searle\, Wichita State)
DESCRIPTION:I will begin by describing a number of important examples of isometric actions of circles in Euclidean space and their restrictions to subspaces of Euclidean space. The goal of the talk will be to see how isometric actions of circles and tori can be used to “recognize” the space on which they are acting.

SUMMARY:Applications of Cayley Digraphs to Waring's Problem and Sum-Product Formulas (Yesim Demiroglu\, Harvey Mudd)
DESCRIPTION:Abstract: In this talk\, we first present some elementary new proofs (using Cayley digraphs and spectral graph theory) for Waring’s problem over finite fields\, and explain how in the process of re-proving these results\, we obtain an original result that provides an analogue of Sarkozy’s theorem in the finite field setting (showing that any subset E of a finite field Fq for which |E| >  (qk)/sqrt{q – 1}must contain at least two distinct elements whose difference is a kth power). Once we have our results for finite fields\, we apply some classical mathematics to extend our Waring’s problem results to the context of general (not  necessarily commutative) finite rings. In the second half of our talk\, we present our sum-product results related to matrix rings over finite fields\, which can again be proven using Cayley digraphs and spectral graph theory in an efficient way.

SUMMARY:Modeling Mechanisms of Ovulatory (Dys)Function (Erica Graham\, Bryn Mawr College)
DESCRIPTION:A normally functioning menstrual cycle requires significant crosstalk between hormones originating in ovarian and brain tissues. Reproductive hormone dysregulation may disrupt function and can lead to infertility\, as occurs in the common endocrine disorder polycystic ovarian syndrome (PCOS). In this talk\, I will discuss a mathematical model of the ovulatory cycle that accounts for mechanisms of ovarian testosterone production and explore insulin-mediated ovulatory dysfunction.  I will also explore additional model characteristics\, via bifurcations and parameter sensitivity\, and their respective clinical implications.

SUMMARY:Snow Business: Scientific Computing in the Movies and Beyond (Joseph Teran\, UCLA)
DESCRIPTION:New applications of scientific computing for solid and fluid mechanics problems include simulation of virtual materials in movie visual effects and virtual surgery. Both disciplines demand physically realistic dynamics for materials like water\, smoke\, fire\, and soft tissues. New algorithms are required for each area. Teran will speak about the simulation techniques required in these fields and will share some recent results including: simulated surgical repair of biomechanical soft tissues; extreme deformation of elastic objects with contact; high resolution incompressible flow; and clothing and hair dynamics. He will also discuss a new algorithm used for simulating the dynamics of snow in Disney’s animated feature film\, “Frozen.”

SUMMARY:An Algebra of Arcs and Knots on a Surface (Helen Wong\, CMC)
DESCRIPTION:The end of the previous century saw radical changes to three-dimensional topology\, which arose from two completely different approaches. One breakthrough came from Bill Thurston’s introduction of hyperbolic geometry into the field. The second one came from the Vaughn Jones’s discovery of a new “quantum” invariant for knots that brought in insight and techniques from mathematical physics and non-commutative algebra. It is widely believed that the two approaches are related. \nIn this talk\, we will focus on a point of connection introduced over five years ago by J. Roger and T. Yang.  They defined an algebra of arcs and knots on a surface that is both  obviously related to the quantum invariants and motivated by hyperbolic geometry.  We will give a overview of what’s known about this algebra of arcs and knots on a surface.  Warning: there will be lots of pictures of arcs and knots on surfaces.
