SUMMARY:Applied Math Seminar — Selenne Bañuelos (Cal State University Channel Islands and Institute for Pure and Applied Mathematics\, UCLA)
DESCRIPTION:Title: Exploring Phage Treatment for Bacterial Infections with Mathematical Modeling \nAbstract: \nAntimicrobial resistance (AMR) is a serious threat to global health today. A renewed interest in phage therapy – the use of bacteriophages to treat pathogenic bacterial infections – has emerged given the spread of AMR and lack of new drug classes in the antibiotic pipeline. This talk will feature mathematical models from an ongoing research project that began in 2019 during the Collaborative Workshop for Women in Mathematical Biology at IPAM.  The first model considers the effect of phage-antibiotic combination therapy. We utilized this model to examine the role of the immune response in concert with phage-antibiotic combination therapy compounded with the effects of the immune system on the phages being used for treatment.  We will then discuss our current work as we collaborate with an experimental biologist.  This model investigates the bacteria-phage interaction in vitro.  We will discuss how our model has given insights into the challenges that arise from limited information in clinical trials\, and the delightful experience of how experimental biologists and applied mathematicians provide guidance to each other to move the project forward.

SUMMARY:Counting points in discrete subgroups (Jeff Vaaler\, UT Austin)
DESCRIPTION:We consider the problem of comparing the number of discrete points that belong to a set with the measure (or volume) of the set\, under circumstances where we expect these two numbers to be approximately equal. We start with a locally compact\, abelian\, topological group G. We assume that G has a countably infinite\, torsion free\, discrete subgroup H. But to make the talk easier to follow we will mostly consider the case G = R^N and H = Z^N. If E ⊆ R^N is a subset there are many situations where one expects that the (finite\, positive) number Vol_N (E) is approximately equal to the cardinality |E ∩ Z^N |. We will sketch the proof of a general result that bounds the difference between these quantities. If k is an algebraic number field and k_A is the ring of adeles associated to k\, this general result is useful when G = k_A^N and H = k^N .

SUMMARY:Topological descriptions of protein folding (Prof. Helen Wong)
DESCRIPTION:Title: Topological descriptions of protein folding\nSpeaker:  Prof. Helen Wong\, Department of Mathematical Sciences\, Claremont-McKenna College. \nAbstract: 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. Unfortunately\, little is known about how proteins fold into knotted configurations. In this talk\, we approach this problem from a theoretical point of view\, using techniques from the mathematical study of shape: Topology. We’ll discuss the topological tools currently used to quantify the complexity and depth of knotting in proteins\, and compare and contrast topological descriptions of proposed pathways for proteins to form knots. \n\nHelen Wong is an Associate Professor of Mathematics in the Department of Mathematical Sciences at Claremont McKenna College and an alumna of Pomona College. Her research is in low-dimensional quantum topology\, and applications of topology to molecular biology and quantum computation. She is particularly interested in the relationship between quantum invariants and related constructions (especially the Kauffman bracket skein algebra of a surface) and non-quantum invariants from topology and hyperbolic geometry.

SUMMARY:Applied Math Seminar -- Sara Clifton (St. Olaf College)
DESCRIPTION:Title: Understanding Complex Social Systems using Minimal Mathematical Models \nAbstract: \nMinimal mathematical models are used to understand complex phenomena in the physical\, biological\, and social sciences. This modeling philosophy never claims\, nor even attempts\, to fully capture the mechanisms underlying the phenomena\, and instead offers insights and predictions not otherwise possible. Here\, we explore minimal dynamical systems models to understand several complex social phenomena\, including the profit-driven abandonment of restaurant tipping\, the public health tradeoffs of e-cigarettes\, and the progression of women through professional hierarchies. Because of their simplicity\, these models offer new connections between existing fields\, give optimal solutions with limited data\, and provide qualitative predictions of future events.

SUMMARY:The Chow ring of heavy/light Hassett spaces via tropical geometry (Dagan Karp\, HMC)
DESCRIPTION:Hassett spaces in genus 0 are moduli spaces of weighted pointed stable rational curves; they are important in the minimal model program and enumerative geometry. We compute the Chow ring of heavy/light Hassett spaces. The computation involves intersection theory on the toric variety corresponding to a graphic matroid\, and rests upon the work of Cavalieri-Hampe-Markwig-Ranganathan. This is joint work with Siddarth Kannan and Shiyue Li.

SUMMARY:Projections on Banach spaces and a lifting property of operators (Prof. Botelho)
DESCRIPTION:Title: Projections on Banach spaces and a lifting property of operators \nProf. Maria Fernanda Botelho\nDepartment of Mathematical Sciences\nThe University Of Memphis \nAbstract: In this talk I will present properties of contractive projections and explain their role in the existence of norm preserving lifts of operators. A pair of Banach spaces (X\, J)\, with J a closed subspace of X\, has the quotient lifting property (QLP) iff for every space Y and S ∈ L(Y\, X/J)\, there is Ŝ  ∈ L(Y\, X)such that S = π ◦ Ŝ\, where π denotes the quotient map from X onto X/J. This property was motivated by Lindenstrauss and Tzafriri lifting property for Banach spaces. \nA pair of Banach spaces (X\,J) has the QLP iff J is the kernel of a contractive projection on X. Several illustrative examples will be discussed. \n\n\n\n  \nBio-Sketch for Fernanda Botelho: \nI am a full professor in the Department of Mathematical Sciences at the University of Memphis. I earned a Doctor of Philosophy degree in Mathematics from the University of California at Berkeley and I did my undergraduate studies at the Universidade do Porto\, Portugal.  \nMy main research interest is in Operator Theory and Functional Analysis. I have authored and co-authored more than 80 research articles. I was a Donavant Professor in 2013-2016.  I have been the coordinator for the Mathematical Sciences Graduate Programs since 2015. \nI participated and organized several conferences\, funded by the National Sciences Foundation and in collaboration with the Association for Women in Mathematics.

SUMMARY:Applied Math Seminar -- Christopher Miles (UC Irvine)
DESCRIPTION:Title:  Collective motion in the mitotic spindle \nAbstract:  Math models of interacting individuals moving as a collective have been profoundly successful in describing physical and social phenomena ranging from swarming insects to human crowds. Especially in molecular biology\, recent advances in machine-learning-based automated tracking have led to droves of new data of collective motion. I’ll discuss two related projects\, both studying chromosomes (DNA) moving during mitosis (cell division). The first project will hopefully convince you that modeling this system as a collective is interesting\, exploring how collective motion models might describe how cancer cells avoid death. The second project will try to address how to actually incorporate data into the modeling process now that we have it.

SUMMARY:On sparse representation of vectors in lattices and semigroups (Iskander Aliev\, Cardiff University)
DESCRIPTION:We will discuss the sparsity of the solutions to systems of linear Diophantine equations with and without non-negativity constraints. The sparsity of a solution vector is the number of its nonzero entries\, which is referred to as the 0-norm of the vector. Our main results are new improved bounds on the minimal 0-norm of solutions to systems Ax=b\, where A is an integer matrix\, b is an integer vector and x is either a general integer vector (lattice case) or a non-negative integer vector (semigroup case). The talk is based on a joint work with G. Averkov\, J. A. De Loera and T. Oertel.

SUMMARY:Collective Behavior in Locust Swarms from Data to Differential Equations (Prof. Jasper Weinburd)
DESCRIPTION:Title: Collective Behavior in Locust Swarms from Data to Differential Equations\n  \nProf. Jasper Weinburd\nDepartment of Mathematics\nHarvey Mudd College\n\n  \n\nAbstract: Locusts are devastating pests that infest and destroy crops. Locusts forage and migrate in large swarms which exhibit distinctive shapes that improve efficiency on the group level\, a phenomenon known as collective behavior. One of the difficulties in understanding and preventing these collective behaviors has been a lack of biological data for individual interactions between locusts.  In this talk\, I’ll first describe mathematical models for these phenomena on both the collective and individual levels. I’ll then discuss a collaboration with students at Harvey Mudd College using field data derived from video footage of locust swarms. We digitized nearly 20\,000 locust trajectories and revealed individual behaviors that depend on a locust’s motion and the relative position of its nearby neighbors. Finally\, I will illustrate the challenges and potential benefits of incorporating these field observations into our models of locust swarms.\n\n\n\n\n\nProf. Jasper Weinburd is an NSF Postdoctoral Fellow at Harvey Mudd College. He received his PhD from the University of Minnesota. In his research he uses dynamical systems\, differential equations\, and data science to model natural phenomena of self-organization. He loves hiking in the San Gabriel Mountains with his dog\, but he still hasn’t climbed Mt. Baldy.

SUMMARY:Odd subgraphs are odd (Asaf Ferber\, UC Irvine)
DESCRIPTION:In this talk we discuss some problems related to finding large induced subgraphs of a given graph G which satisfy some degree-constraints (for example\, all degrees are odd\, or all degrees are j mod k\, etc). We survey some classical results\, present some interesting and challenging problems\, and sketch solutions to some of them. This is based on joint works with Michael Krivelevich\, and with Liam Hardiman and Michael Krivelevich.
