SUMMARY:Applied Math Talk: Variable Selection via Arbitrary Rectangle-Range Generalized Elastic Net given by Yujia Ding (CGU)
DESCRIPTION:We propose a regularization and variable selection method\, named arbitrary rectangle-range generalized elastic net (ARGEN). It can be applied in high dimensional sparse linear regression models. We propose an algorithm to solve ARGEN; it is an extension of multiplicative updates. Multiple simulation studies and a real-world application in the stock market show that ARGEN applies to more complicated problems\, outperforms and extends the lasso\, ridge\, and elastic net.

SUMMARY:Finding bases of new infinite dimensional representations of $\mathfrak{osp}(1|2n)$ ( Dwight Williams\, UT Arlington)
DESCRIPTION:The orthosymplectic Lie superalgebra $\mathfrak{osp}(1|2n)$ is rich in representation theory: while the finite dimensional $\mathfrak{osp}(1|2n)$-module category is semisimple\, the study of infinite dimensional representations of $\mathfrak{osp}(1|2n)$ is wide open. In this talk\, we will define the orthosymplectic Lie superalgebras\, realize $\mathfrak{osp}(1|2n)$ as differential operators on complex polynomials\, and describe the space of polynomials in commuting and anti-commuting variables as a representation space for $\mathfrak{osp}(1|2n)$. Moreover\, we will present operators—and perhaps generalized versions of these operators—which help give explicit bases for certain infinite dimensional $\mathfrak{osp}(1|2n)$-modules.

SUMMARY:(Cancelled!!) Applied Math Talk: Stable planar vegetation stripe patterns on sloped terrain in dryland ecosystems given by Prof. Paul Carter (University of Minnesota)
DESCRIPTION:In water-limited regions\, competition for water resources results in the formation of vegetation patterns; on sloped terrain\, one finds that the vegetation typically aligns in stripes or arcs. The dynamics of these patterns can be modeled by reaction-diffusion PDEs describing the interplay of vegetation and water resources\, where sloped terrain is modeled through advection terms representing the downhill flow of water. We focus on one such model in the ‘large-advection’ limit\, and we prove the existence of traveling planar stripe patterns using analytical and geometric techniques. We also discuss implications for the stability of the resulting patterns\, as well as the appearance of curved stripe solutions.

SUMMARY:Graph coloring reconfiguration systems (Prateek Bhakta\, University of Richmond)
DESCRIPTION:For k >= 2\, the k-coloring graph C(G) of a base graph G has a vertex set consisting of the proper k-colorings of G with edges connecting two vertices corresponding to two different colorings of G if those two colorings differ in the color assigned to a single vertex of G. A base graph whose k-coloring graph is connected is called k-mixing; here it is possible to reconfigure a particular k-coloring of G to any other k-coloring of G by changing the color of one vertex at a time in the assignment while maintaining that each intermediate step is a proper k-coloring. We explore the connectivity and biconnectivity of coloring graphs with a focus on the inverse problem: given a graph H\, is H the k coloring graph of some base graph G for some k?

SUMMARY:Applied Math Talk: Approaches to modeling dispersal and swarm behavior at multiple scales given by Prof. Christopher Strickland ( The University of Tennessee\, Knoxville)
DESCRIPTION:Biological invasions often have outsized consequences for the invaded ecosystem and represent an interesting challenge to model mathematically. Landscape heterogeneity\, non-local or time-dependent spreading mechanisms\, coarse data\, and air or water flow transport are but a few of the complications that can greatly affect our understanding of small organism movement – a critical component of both invasion success and the ability of native organisms to persist at a location. In this talk\, I will look at dispersal and swarm behavior from a multi-scale\, mathematical perspective in order to address some of these challenges. \nConsidering the problem of long-distance dispersal\, I will discuss a method for modeling invasive spread over large\, heterogeneous landscapes by interpreting the quantity of interest as the probability of species occurrence rather than population size. On large scales\, one can also take advantage of ecological niche modeling approaches in order to reduce the dimensionality of data quantifying landscape heterogeneity. I will then shift focus to the initial stages of an invasion and concentrate on the local- and meso-scale by considering the intentional release of a parasitoid wasp biocontrol agent. In this case\, we can utilize a Bayesian framework and maximum likelihood estimation to parameterize the model based on proxy time-series data collected in the field. Finally\, I will describe some of my current work close to the microscale examining the dynamics of organism movement and behavior with respect to a surrounding fluid environment.

SUMMARY:On badly approximable numbers (Nikolai Moshchevitin\, Moscow State University)

Motivated by a recent wonderful paper by Ngoc Ai Van Nguyen\, Anthony Poels and Damien Roy (where the authors give a simple alternative solution of Schmidt-Summerer’s problem) we found an unusual generalization of this criterion for badly approximable d-dimensional vectors.

SUMMARY:Applied Math Talk: Information Theory\, Archetypal Analysis and MT Flu given by Professor Emily Stone (University of Montana-Missoula)
DESCRIPTION:In this talk I will discuss a rather unique collection of tools and how they have been used to understand the spread of Influenza virus in the State of Montana.  With flu counts from each county over a 10 year period some patterns emerge\, which explain some vectors of the disease spread.  Archetypal analysis then creates reduced dimension sets\, and the dynamics of the flu spread can be understood by parameterizing SIR models with the reduced data.

SUMMARY:Applied Math Talk: Robust Estimators for Monte Carlo data given by Prof.  Mark Huber (CMC)
DESCRIPTION:Data coming from Monte Carlo experiments is often analyzed in the same way as data from more traditional sources.  The unique nature of Monte Carlo data\, where it is easy to take a random number of samples\, allows for estimators where the user can control the relative error of the estimate much more precisely than with classical approaches.  In this talk I will discuss three such estimators useful in different problems.  The first is a user-specified-relative-error (USRE) estimate for the mean of a Bernoulli random variable.  This allows us to obtain exact error results while using slightly fewer samples than the CLT approximation.  The second is more general\, applying to any random variable where a bound on the relative error is known.  For this problem we give exact error bounds using a number of samples that is the same (to first order) as the CLT approximation requires.  In other words\, the new algorithm is the equivalent of always actually having normal data.  Finally\, we look at the problem of data with unknown variance and develop an algorithm that runs very close to the minimum number of samples established by results of Wald.

SUMMARY:Covering point-sets with parallel hyperplanes and sparse signal recovery (Lenny Fukshansky\, CMC)
DESCRIPTION:Let S be a set of k > n points in n-dimensional Euclidean space. How many parallel hyperplanes are needed to cover it? In fact\, it is easy to prove that every such set can be covered by k-n+1 parallel hyperplanes\, but do there exist sets that cannot be covered by fewer parallel hyperplanes? We construct a family of examples of such extremal sets. We then use it\, along with a result on girth of bipartite graphs\, to construct a family of n x d integer matrices with bounded sup-norm and the property that no m column vectors are linearly dependent\, m < n. If m < (log n)^{1-e} for any e > 0\, then d/n tends to infinity as n tends to infinity. This is a deterministic construction of a family of sensing matrices\, which are used for sparse signal recovery in compressed sensing. Joint work with Alex Hsu.

SUMMARY:Castelnuovo-Mumford regularity of edge ideals of graphs (Siamak Yassemi\, University of Tehran)
DESCRIPTION:Let K be a field and S = K[x_1\,…\,x_n] be the polynomial ring in n variables over K. For a graded S-module M with minimal free resolution the Castelnuovo-Mumford regularity  is defined. We survey a number of recent studies of the Castelnuovo-Mumford regularity of the ideals related to a graph and their (symbolic) powers. Our focus is on the bounds and exact values for the regularity in terms of combinatorial data from associated graphs. This research program has produced many exciting results and\, at the same time\, opened many further interesting questions and conjectures.

SUMMARY:Applied Math Talk:  Statistical Mechanics of Molecular Evolution and its Role in the SELEX Protocol given by Prof. Bhaven Mistry (CMC)
DESCRIPTION:Antibodies are the standard biomolecule for marking molecular structures and delivering drugs due to their specific binding capabilities. However\, they are expensive to produce and their relatively large size prevents their easy traversal of bi-lipid membranes. Over the past 30 years\, molecular recognition has also been achieved through the use of aptamers\, short oligonucleotide sequences that fold in conformations that allow them to specifically bind to targets. These aptamers are produced rapidly and efficiently through a process known as Systematic Evolution of Ligands by EXponential enrichment (SELEX) whereby a molecular selection mechanism based on competitive binding enriches the population of given strands and removes unwanted sequences\, yielding high target specificity and affinity. Current SELEX mathematical models are formulated in the mass action limit\, which assumes large aptamer/target concentrations. Low number effects\, such as the extinction probability of the best binding aptamer\, however\, require a full stochastic model currently lacking in the literature. We derive such a statistical mechanics model verifying that in the large aptamer/target concentration limit\, the mass action results are recovered. Our stochastic model also allows us to calculate the extinction probability and efficiency of selection\, and to propose a method of optimizing the SELEX protocol.

SUMMARY:Dragging the roots of a polynomial to the unit circle (Sinai Robins\, University of Sao Paulo)
DESCRIPTION:Several conditions are known for a self-inversive polynomial that ascertain the location of its roots\, and we present a framework for comparison of those conditions. We associate a parametric family of polynomials p_α(x) to each such polynomial p\, and define cn(p)\, il(p) to be the sharp threshold values of α that guarantee that\, for all larger values of the parameter\, p_α(x) has\, respectively\, all roots in the unit circle and all roots interlacing the roots of unity of the same degree.  Interlacing implies circle rootedness\, hence il(p) ≥ cn(p)\, and this inequality is often used for showing circle rootedness. Both il(p) and cn(p) turn out to be semi-algebraic functions of the coefficients of p\, and some useful bounds are also presented\, entailing several known results about roots in the circle. The study of il(p) leads to a rich classification of real self-inversive polynomials of each degree\, organizing them into a complete polyhedral fan. We have a close look at the class of polynomials for which il(p) = cn(p)\, whereas in general the quotient il(p)/cn(p) is shown to be unbounded as the degree grows. Several examples and open questions are presented.  This is joint work with Arnaldo Mandel.

SUMMARY:Computational bounds for doing harmonic analysis on permutation modules of finite groups (Mike Orrison\, HMC)
DESCRIPTION:In this talk\, I will describe an approach to finding upper bounds for the number of arithmetic operations necessary for doing harmonic analysis on permutation modules of finite groups. The approach takes advantage of the intrinsic orbital structure of permutation modules\, and it uses the multiplicities of irreducible submodules within individual orbital spaces to express the resulting computational bounds. I will then conclude by showing that these bounds are surprisingly small when dealing with certain permutation modules arising from the action of the symmetric group on tabloids. This is joint work with Michael Hansen\, Masanori Koyama\, Matthew McDermott\, and Sarah Wolff.

SUMMARY:Applied Math Talk: Set your parasites low (or high) given by Professor Maryann Hohn (Pomona College)
DESCRIPTION:Individuals may choose to create social groups where their individual fitness and success is influenced by those around them.  A group may increase an individual’s success in finding food\, shelter\, and safety; however\, if the group fails\, so does the individual.  In this talk\, we will explore how choices of individuals influence group dynamics using both agent-based modeling and partial differential equations.  In particular\, we will examine individuals who live in close\, collaborate groups who are susceptible to infectious diseases such as pathogens and parasites through their social network.

SUMMARY:Applied Math Seminar On Unlimited Sampling given by Prof. Felix Krahmer (Technische Universität München)
DESCRIPTION:Shannons sampling theorem provides a link between the continuous and thediscrete realms stating that bandlimited signals are uniquely determined by itsvalues on a discrete set. This theorem is realized in practice using so called analog to digital converters (ADCs). Unlike Shannons sampling theorem\, the ADCs are limited in dynamic range. Whenever a signal exceeds some preset threshold\, the ADC saturates\, resulting in aliasing due to clipping. In this talk\,we analyze an alternative approach that does not suffer from these problems.Our work is based on recent developments in ADC design\, which allow for ADCs that reset rather than to saturate\, thus producing modulo samples. An open problem that remains is: Given such modulo samples of a bandlimited function as well as the dynamic range of the ADC\, how can the original signal be recovered and what are the sufficient conditions that guarantee perfect recovery? In this paper\, we prove such sufficiency conditions and complement them with a stable recovery algorithm. Our results not limited to certain amplitude ranges\, in fact even the same circuit architecture allows for the recovery of arbitrary large amplitudes as long as some estimate of the signal norm is available whenrecovering. \nThis is joint work with Ayush Bhandari (Imperial College London) and Ramesh Raskar (MIT). \nBio: \nFelix Krahmer received his PhD in Mathematics in 2009 from New York University under the supervision of Percy Deift and Sinan Güntürk. He was a Hausdorff postdoc in the group of Holger Rauhut at the University of Bonn\, Germany from 2009-2012. In 2012 he joined the University of Göttingen as a an assistant professor for mathematical data analysis\, where he has been awarded an Emmy Noether Junior Research Group. Since 2015 he has been tenure track assistant professor for optimization and data analysis in the department of mathematics at the Technical University of Munich.

SUMMARY:Exponential domination in grids (Michael Young\, Iowa State University)
DESCRIPTION:Domination in graphs has been an important and active topic in graph theory for over 40 years. It has immediate applications in visibility and controllability. In this talk we will discuss a generalization of domination called exponential domination. A vertex $v$ in an exponential dominating set assigns weight $2^{1−dist(v\,u)}$ to vertex $u$. An exponential dominating set of a graph $G$ is a subset of $V(G)$ such that every vertex in $V(G)$ has been assigned a sum weight of at least 1. We will specifically look at grid graphs and graphs on the torus.

SUMMARY:Applied Math Talk: Patterns deformed by spatial inhomogeneity give by Prof. Jasper Weinburd (HMC)
DESCRIPTION:At the turn of the twentieth century\, physicist Henri Bénard heated a shallow plate of fluid from below. For temperatures above a critical value\, the fluid’s evenly heated state became unstable as thermal convection took hold; heated fluid rose in localized areas while cooler fluid fell nearby. The rising and falling fluid created hexagonal convection cells\, squares\, and stripes.\nSuppose that we modify Bénard’s experiment by heating only the left half plate. We expect the fluid on the right to remain stationary and only the the fluid on the left to form patterns. We confirm this intuition mathematically and\, more surprisingly\, find that the step-type inhomogeneity restricts the spatial period of the resulting patterns on the left. We examine this phenomenon using a universal partial differential equation model. The main difficulty arrises at the location of the discontinuous inhomogeneity because results on either side cannot be directly compared. We construct a transformation of variables that bridges this jump and allows a heteroclinic glueing argument from left to right. The explicit form of this transformation determines the widths of patterns that may occur in the inhomogeneous environment.
