• Applied Math Talk: Set your parasites low (or high) given by Professor Maryann Hohn (Pomona College)

    Emmy Noether Room, Millikan 1021, Pomona College 610 N. College Ave., Claremont, California

    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 […]

  • Computational bounds for doing harmonic analysis on permutation modules of finite groups (Mike Orrison, HMC)

    Emmy Noether Room, Millikan 1021, Pomona College 610 N. College Ave., Claremont, California

    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 […]

  • Epidemiological models for Ebola exploring different dynamics

    Argue Auditorium, Pomona College 610 N. College Ave., Claremont, CA, United States

    In today's environment of universal connection and media updates, we are constantly informed about infectious diseases and the ramifications. We can combat infectious diseases using mathematics to gain insight into […]

    The Field Committee Meeting is our chance to socialize with our colleagues and coordinate our course offerings for the coming academic year (2020-2021). Please come to discuss course offerings and […]

  • Dragging the roots of a polynomial to the unit circle (Sinai Robins, University of Sao Paulo)

    Emmy Noether Room, Millikan 1021, Pomona College 610 N. College Ave., Claremont, California

    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 […]

  • Castelnuovo-Mumford regularity of edge ideals of graphs (Siamak Yassemi, University of Tehran)

    Emmy Noether Room, Millikan 1021, Pomona College 610 N. College Ave., Claremont, California

    Let K be a field and S = K 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 […]

  • Stefano Vidussi (UCRiverside)

    Title: The BNS invariant of the fundamental group of a surface bundle over a surface. Abstract: We will discuss some new results on the Bieri-Neumann-Strebel invariant of these groups, showing in particular that (with obvious exceptions) they algebraically fiber. As a corollary, we show that for "most" bundles these groups are not coherent.

  • A Tauberian theorem and some of its applications

    Freeberg Forum, LC 62, Kravis Center, CMC

    In general terms, a Tauberian theorem deals with the relationship between the properties of one transform of a measure with those of another transform. We will introduce the notion of […]

  • Covering point-sets with parallel hyperplanes and sparse signal recovery (Lenny Fukshansky, CMC)

    Emmy Noether Room, Millikan 1021, Pomona College 610 N. College Ave., Claremont, California

    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 […]
