SUMMARY:Applied Math Seminar: Ruijun Zhao (Claremont McKenna College)
DESCRIPTION:Title: Mathematical models studying the effectiveness of control strategies for malaria \nAbstract: According to the 2023 World Malaria Report: Nearly half the world’s population lives in areas at risk of malaria transmission in 85 countries and territories. In 2022\, malaria caused an estimated 249 million clinical episodes\, and 608\,000 deaths. In this talk\, we will discuss a few mathematical models that study the effectiveness of control strategies such as vaccines and insecticide-treated bednets. We will also discuss a model to understand the interplay between malaria dynamics\, economic growth\, and transient events. The challenges when conducting mathematical analysis and numerical simulation will also be discussed.

SUMMARY:Making sandwiches: a novel invariant in D-module theory (David Lieberman\, HMC)
DESCRIPTION:In the field of commutative algebra\, the principal object of study is (unsurprisingly) commutative algebras. A somewhat unintuitive fact is that results about commutative algebras can be gleaned from an associated non-commutative algebra whose generators are very analytic in nature. This object is called the ring of differential operators\, often denoted by D. In a sense gives an algebraic way of constructing the partial derivative.\n\nAn important result in the study of D-modules is Bernstein’s inequality\, first proved by Joseph Bernstein in the 1970’s. The result gives a lower bound on the filtered dimension of a D-module\, which a provide insights about modules of commutative algebras. The goal of this talk is to present some novel singular settings where this inequality holds. To do this\, we will introduce an invariant called sandwich Bernstein-Sato polynomials. These are analogous to a well studied object called the Bernstein-Sato polynomial\, which is a generalization of the power rule taught in undergraduate calculus courses. Using sandwich Bernstein-Sato polynomials\, we will show that Bernstein’s inequality holds true for the differential operators of the coordinate ring of the Segre product of projective spaces.

SUMMARY:Claremont Topology Seminar: Will Hoffer (UC Riverside)
DESCRIPTION:We welcome all undergraduate/graduate students and faculty to attend topology seminar! \nSpeaker: Will Hoffer (UC Riverside) \nTitle: Tube Formulae for Fractal Snowflakes \nAbstract: Fractals like the von Koch snowflake have rough boundaries\, often having nowhere defined tangent lines/spaces. However\, there is a tool useful for probing the edges of such fractals: tubular neighborhoods. In this talk\, we’ll introduce the theory of fractal tube formulae which describe the volumes of such tubular neighborhoods\, illustrating through our recent work on generalized fractal snowflakes. In the process\, we’ll touch on the theory of complex dimensions and tubular zeta functions that capture the (multiplicative) oscillations appearing in the geometry of fractals.

SUMMARY:Frameworks in Motion: Design\, Theory\, and Fabrication (Jessica Sidman\, Amherst College
DESCRIPTION:Speaker: Jessica Sidman\, Professor of Mathematics and Computer Science\, Amherst College \nTitle: Frameworks in Motion: Design\, Theory\, and Fabrication \nAbstract: What do your umbrella\, a folding gate\, and a scissor lift have in common? They all involve frameworks made of rigid parts attached at flexible joints and are designed to move with one degree of freedom. In 1981 architect Santiago Calatrava wrote a PhD thesis\, “Concerning the Foldability of Space Frames\,” containing a systematic exploration of the geometry and design of foldable frameworks. I’ll use his thesis as a jumping off point to explore the Geiringer-Laman Theorem and ideas for further research.\n \nBio:  Jessica Sidman loves to work on pure and applied problems at the intersection of computational algebra\, algebraic geometry\, and combinatorics. Her recent work in rigidity theory combines aspects of these three fields\, and all got started when an undergraduate doing a thesis on protein folding asked her a question about projective space. She got her B.A. from Scripps College\, a Ph.D. from the University of Michigan\, and did postdoctoral work at UC Berkeley and UMass Amherst.  She was the Professor of Mathematics on the John Stewart Kennedy Foundation at Mount Holyoke College and is now the Brian E. Boyle Professor in Mathematics and Computer Science at Amherst College.
