SUMMARY:Geometry of quotient varieties and the algebra of conformal blocks (Han-Bom Moon Fordham University)
DESCRIPTION:An important question in classical representation theory is when the tensor product of two irreducible representations has another representation as a factor. In this talk\, I will introduce a quantum generalization of this question and explain how we may relate this question to geometry of quotients of certain complex manifolds. This is joint work with Sang-Bum Yoo.

SUMMARY:GEMS Workshop: "Graphs\, matrices\, and recurrences" with Professor Lucas Bang\, from Harvey Mudd College
DESCRIPTION:TOPIC: Graphs\, matrices\, and recurrences \nAbstract: In mathematics\, we are often surprised to find that problems that look very different are actually the same problem in a different guise! In this seminar\, we will build on the previous discussions about graph theory and describe how other areas of math are closely related to graphs. Specifically\, we will learn how graph problems can be translated to and from matrix problems. We will also see how both graphs and matrices are related to recursive integer sequences (like the famous Fibonacci numbers). \nWHAT IS GEMS: \nThe Gateway to Exploring Mathematics program (GEMS) is a series of workshops that helps excite the interests and curiosity of young students in mathematics and science \nGEMS meets once a month on a Saturday morning from 10:00 AM to 12:00 PM \nGEMS is designed to reach 8th\, 9th and 10th grade students who have an interest in mathematics and science \nParticipants interact with excellent and award winning faculty\, staff\, students and alumni from each of the seven Claremont Colleges \nSPRING 2019 DATES: \nFebruary 2\, 2019 \nMarch 2\, 2019 \nApril 13\, 2019 \nREGISTRATION: \nTo register for our workshop on April 13\, please click on the following link: \nhttps://tinyurl.com/GEMS2019Spring3 \nANY QUESTIONS: \nPlease contact our 2018-2019 GEMS coordinator\, Elsa Harris at Elsa.Harris@cgu.edu

SUMMARY:Applied Math Talk: Solving Complex Public Health Problems—Cancer\, Obesity and Aging (Jessica Dehart\, CGU)
DESCRIPTION:Abstract: Remember smoking? What’s the new public health problem? In the US\, we are currently entangled within three converging and intertwined complex problems: Cancer\, Obesity\, Aging. There are over 16 million cancer survivors living in the US as we speak. Over 50% of our society is overweight and/obese. Our society is aging and the age distribution is much older than a few years back. Cancer\, obesity and aging share several risk factors\, biological mechanisms and patterns. Given the multidimensionality and complexity of these issues\, only a transdisciplinary approach will have the best chances of success in sustaining a health society. This talk will discuss the problems and potential transdisciplinary approaches—including math—to finding successful solutions.

SUMMARY:Enhancements of the quandle coloring invariant for knots (Karina Cho\, Harvey Mudd College)
DESCRIPTION:Quandles are algebraic structures that play nicely with knots. The multiplicative structure of finite quandles gives us a way to “color” knot diagrams\, and the number of such colorings for a given knot and quandle is called the quandle coloring invariant. We strengthen this invariant by examining the relationships between the colorings\, which are given by endomorphisms. This can be visualized using a directed graph that we call the quandle coloring quiver. We will show that the quandle coloring quiver is a strict enhancement of the quandle coloring invariant and discuss further enhancements of this invariant that arise from quandle cohomology. This work is a senior thesis project under the advising of Sam Nelson.

SUMMARY:Applied Math Talk: Nonlocal problems for linear evolution equations (Prof. Smith David Andrew\, Yale-NUS College\, Singapore)
DESCRIPTION:Linear evolution equations\, such as the heat equation\, are commonly studied on finite spatial domains via initial-boundary value problems. In place of the boundary conditions\, we consider “multipoint conditions”\, where one specifies some linear combination of the solution and its derivative evaluated at internal points of the spatial domain\, and “nonlocal” specification of the integral over space of the solution against some continuous weight.

SUMMARY:Theory of vertex Ho-Lee-Schur graphs (Sin-Min Lee\, SJSU)
DESCRIPTION:A triple of natural numbers (a\,b\,c) is an S-set if a+b=c. I. Schur used the S-sets to show that for n >3\, there exists s(n) such that for prime p > s(n)\, x^p + y^p = z^p (mod p) has a nontrivial solution. A (p\,q)-graph G is said to be vertex Ho-Lee-Schur graph if there exists a bijection f: V(G) –> {1\,2\,…\,p} such that for each C3 subgraph of G with vertices {x\,y\,z} the triple (f(x)\,f(y)\,f(z)) is an S-set. The VHLS deficiency of G is the smallest k such that GU Nk\, where Nk is null graph\,  is a vertex Ho-Lee-Schur graph. We determine VHLS deficiency of some graphs and show that no Kuratowski type characterization of non-vertex Ho-Lee-Schur graphs. Some relation of integer partitions and this theory  is explored. We will also introduce some unsolved problems and invite the audience to  solve them.

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 (Z⊕Z)-family of knot quandles (Jim Hoste\, Pitzer College)
DESCRIPTION:Suppose K is an oriented knot in a 3-manifold M with regular neighborhood N (K). For each element γ ∈ π 1 (∂N (K)) we define a quandle Q γ (K; M) which generalizes the concept of the fundamental quandle of a knot. In particular\, when γ is the meridian of K\, we obtain the fundamental quandle. The collection of all such quandles gives a (Z⊕Z)-family of quandles. If K is a knot in M and γ is a primitive element\, then we show that there exists a knot K’ in a 3-manifold M’ such that Q γ (K; M ) ∼= Q μ (K’ ; M’) where μ is the meridian of K’ . Starting with a partially framed link L in the 3-sphere where the framed components give a surgery description of the manifold M and a single unframed component represents K we can derive a similar surgery description of K’ in M’ . Using results of Fenn and Rourke\, we may then use this description of K’ to record a presentation of the quandle Q γ (K; M). We describe a number of examples of these quandles for knots\nin various manifolds.

SUMMARY:Applied Math Seminar: The Kaczmarz Algorithm and its Applications to Data Science (Anna Ma\, UCSD)
DESCRIPTION:Data is exploding at a faster rate than computer architectures can handle. For that reason\, mathematical techniques to analyze large-scale data need be developed. Stochastic iterative algorithms have gained interest due to their low memory footprint and adaptability for large-scale data. In this talk\, we will study the Randomized Kaczmarz algorithm for solving extremely large linear systems of the form Ax=y. In the spirit of large-scale data\, this talk will proceed under the assumption that the entire data matrix A cannot be loaded into memory in a single instance. We consider different settings including when a only factorization of A is available\, when x is sparse\, and a time-varying model. We will also present applications of these Kaczmarz variants to problems in data science.

SUMMARY:What Did Ada Do? Digging into the Mathematical Work of Ada Lovelace (Gizem Karaali\, Pomona)
DESCRIPTION:Augusta Ada Byron King Lovelace (1815-1852) is today celebrated as the first computer programmer in history. This might be confusing to some because in 1852 there were no machines that looked like what we call computers today. In this talk I attempt to explain what Ada really did\, and delineate the mathematics involved. Bernoulli numbers will definitely come into play\, but there may also be other fun distractions along the way\, possibly including some juicy gossip about Ada’s life.

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:Applied math seminar: Topological descriptions of protein folding (Helen Wong\, CMC)
DESCRIPTION:Knotting in proteins was once considered exceedingly rare.  However\, systematic analyses of solved protein structures over the last two decades have demonstrated the existence of many deeply knotted proteins\, and researchers now hypothesize that the knotting presents some functional or evolutionary advantage for those proteins. \n  \nUnfortunately\, there is very little known (whether experimentally\, through computer simulations\, or theoretically) about how proteins fold into knotted configurations.  In this talk\, we will discuss some of the theorized pathways from a topological point of view.  In particular\, we propose a new theoretical pathway for protein knotting and determine its feasibility for certain families of  proteins.

SUMMARY:Notions of stability in algebraic geometry (Jason Lo\, CSUN)
DESCRIPTION:One of the main drivers of current research in geometry is the classification of Calabi-Yau threefolds.  Towards this effort\, a particular approach in algebraic geometry is via the study of stability conditions.  In this talk\, I will explain what constitutes a notion of stability in algebraic geometry\, and what the challenges are in studying them.

SUMMARY:Frobenius problem over number fields (Lenny Fukshansky\, CMC)

This problem and its various generalizations have been studied extensively in combinatorics\, number theory\, algebra\, theoretical computer science and probability theory. In this talk\, we will consider a reformulation of this problem in the context of number fields\, which leads to some arithmetic questions about semigroups of algebraic integers and height functions. This is joint work with CMC student Edward Shi.

SUMMARY:Applied Math Seminar: A hybrid inverse problem in the fluorescence ultrasound modulated optical tomography given by Yimin Zhong (UCI)
DESCRIPTION:We investigate a hybrid inverse problem in fluorescence ultrasound modulated optical tomography (fUMOT) in the diffusive regime. We prove that the boundary measurement of the\nphoton currents allows unique and stable reconstructions of the absorption coefficient of the fluorophores at the excitation frequency and the quantum efficiency coefficient simultaneously\, provided\nthat some background medium parameters are known. Reconstruction algorithms are proposed and\nnumerically implemented as well.

SUMMARY:Introduction to theory of Euclid graphs (Sin-Min Lee\, SJSU)
DESCRIPTION:In Euclidean geometry\, the sum of  two sides of any  triangle is greater than the third side. We  introduce this idea to labeling of graphs. A (p\,q)-graph G=(V\,E) is said to be in Euclid(0) if there exists a bijection f: V(G) –> {1\,…\,p} such that for each induced C3 subgraph with vertices {v1\,v2\,v3} with f(v1)<f(v2)<f(v3) we have \nf(v1)+f(v2)>f(v3) . \nFor k > 1\, G is in Euclid(k) class of graphs if there exits smallest k such that G U Nk in Euclid(0)\, where Nk is the null graph with k isolated points. We exhibit infinitely many graphs in Euclid(k) for each k. The talk is target to general audiences. Several open problems will posed for future research. The report is the joint work with several high school\, undergraduate students and researchers.

SUMMARY:Topology Seminar: Sam Nelson (CMC)
DESCRIPTION:Title: Biquandle Brackets and Knotoids \nAbstract: Biquandle brackets are a type of quantum enhancement of the  biquandle counting invariant for oriented knots and links\, defined by a set of skein relations with coefficients which are functions of biquandle colors at a crossing. In this talk we use biquandle brackets to enhance the biquandle counting matrix invariant of knotoids. This is joint work with Neslihan Gugumcu (Izmir Institute of Technology\, Izmir\, Turkey) and Natsumi Oyamaguchi (Shumei University\, Tokyo\, Japan).

SUMMARY:Data-driven multiscale modeling of cell fate dynamics
DESCRIPTION:Cells make fate decisions in response to dynamic environmental and pathological stimuli as well as cell-to-cell communications. Recent technological breakthroughs have enabled to gather data in previously unthinkable quantities at single cell level\, starting to suggest that cell fate decision is much more complex\, dynamic\, and stochastic than previously recognized. Multiscale interactions\, sometimes through cell-cell communications\, play a critical role in cell decision making. Dissecting cellular dynamics emerging from molecular and genomic scale in single-cell demands novel computational tools and multiscale models. In this talk\, I will present our recent works on analyzing single cell molecular data\, and their connections with cellular and spatial tissue dynamics. Our mathematical approaches bring together optimization\, statistical physics\, ODEs/PDEs\, and stochastic simulations along with machine learning techniques. By utilizing our newly developed computational tools along with their close integrations with new datasets collected from our experimental collaborators\, we are able to investigate several complex systems during development and regeneration to uncover new mechanisms in cell fate determination.

SUMMARY:Why biologists cant stop saying single-cell and how this is a distinctly mathematical refrain
DESCRIPTION:Single-cell genomics is a catch phrase for numerous new technologies and methods that allow for probing cells at genome scale. I will explain what this means and describe some examples that illustrate the excitement in this new domain. While single-cell genomics technologies draw on methods from a variety of disciplines such asf biology\, chemistry and engineering\, the interpretation of the data they generate requires concepts and tools from statistics\, computer science and mathematics. I will explain some of the connections with a view towards highlighting interesting solved and unsolved problems in the field.

SUMMARY:Combinatorics and representation theory of Temperley-Lieb algebras (Zajj Daugherty\, CUNY)
DESCRIPTION:The classical\, one-boundary\, and two-boundary Temperley-Lieb algebras arise in mathematical physics related to solving certain rectangular lattice models.They also have beautiful presentations as “diagram algebras”\, meaning that they have basis elements depicted as certain kinds of graphs\, and multiplication rules are given by stacking diagrams and gluing of vertices. In this talk\, we will explore these algebras and their representation theory\, as well as their relationship to other important diagram algebras in combinatorial representation theory.

SUMMARY:Topology Seminar: Jesse Levitt (USC)
DESCRIPTION:Title: Understanding Structure in the Single Variable Knot Polynomials \nAbstract: \nWe examine the dimensionality and internal structure of the aggregated data produced by the Alexander\, Jones\, and Z0 polynomials using topological data analysis and dimensional reduction techniques. By examining several families of knots\, including over 10 million distinct examples\, we find that the Jones data is well described as a three dimensional manifold\, the Z0 data as a single two dimensional manifold and the Alexander data as a collection of two dimensional manifolds. We confirm each of these structural results using two independent ‘big data’ techniques. The ability to consider knots in this manner illuminates several interesting relationships that I hope to discuss at the conclusion of the talk. This collects joint work with Mustafa Hajij and Radmila Sazdanovic.

SUMMARY:Freeways and Circle Packing
DESCRIPTION:The beauty of mathematics is often encountered when one discovers that two apparently very different phenomena actually share a common origin. I will discuss such a surprising connection between two apparently unrelated mathematical objects. One is purely combinatorial: the number of ways one can drive from USC to the Claremont Colleges. The other one is geometric: the Ford circle packing\, a pretty configuration of circles in the plane with interesting number theoretic properties.

SUMMARY:Regime transitions of liquid films flowing down a fiber (Applied Math Talk given by Prof. Claudia Falcon\, UCLA)
DESCRIPTION:Recent  experiments  of  thin  films  flowing  down  a  vertical  fiber  with  varying  nozzle diameters present a wealth of new dynamics that illustrate the need for more advanced theory. Determining  the  regime  transitions from absolute (Rayleigh- Plateau) instability is useful in the  design  of  heat  and  mass  exchangers for applications that include cooling systems and desalination. We present a detailed analysis using a full lubrication model that includes slip boundary conditions\, nonlinear curvature terms\, and a film stabilization term. This study brings to focus the presence of a stable liquid layer playing an important role in the full dynamics. We propose a combination of these physical effects to explain the observed velocity  and  stability  of  traveling  droplets  in  the  experiments  and their  transition  to isolated droplets. When thermal gradients are present\, it can induce bead coalescence away from the nozzle. To account for this\, we incorporate spatial-dependent viscosity and surface tension to the model\, due  to  inhomogeneous  temperature  field  along  the  fiber.

SUMMARY:Applied Math Seminar: Mathematical model of Hematopoietic cell differentiation from single-cell gene sequencing data (Prof. Heyrim Cho \,UCR)
DESCRIPTION:Recent advances in single-cell gene sequencing data and high-dimensional data analysis techniques are bringing in new opportunities in modeling biological systems. In this talk\, I will discuss different approaches to develop mathematical models from single-cell data. Particularly for high-dimensional single-cell gene sequencing data\, dimension reduction techniques are applied to find the trajectories of cell states in the reduced differentiation space. Then\, we develop PDE models that describe the cell differentiation as directed and random movement on the abstracted graph or on the reduced space. Normal hematopoiesis differentiation and abnormal processes of acute myeloid leukemia (AML) progression are simulated\, and the model can predict the emergence of cells in novel intermediate states of differentiation consistent with immunophenotypic characterizations of AML. In addition\, we demonstrate that our model is capable to illustrate the reconstitution of impaired Hematopoiesis\, for instance\, after chemotherapy.
