Quantum chromatic numbers of products of quantum graphs (Prof. Rolando De Santiago, Purdue University)

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

Title: Quantum chromatic numbers of products of quantum graphs Speaker: Rolando De Santiago, Department of Mathematics, Purdue University Abstract: Quantum graphs are an operator space generalization of classical graphs that have emerged in different branches of mathematics including operator theory, non-commutative topology and quantum information theory. We provide a brief introduction to quantum graphs and […]

structural aspects of von Neumann algebras arising as graph products (Rolando de Santiago, Purdue University)

Roberts North 105, CMC 320 E. 9th St., Claremont, CA, United States

Graph products of groups were introduced in E. Green’s thesis in the 90’s as generalizations of Right-Angled Artin Groups. These have become objects of intense study due to their key roles in topology and group theory.  Recently, Caspers and Fima introduced graph products of von Neumann algebras. Since their inception, several structural aspects such as […]

On zeros of multilinear polynomials (Max Forst, CGU)

Davidson Lecture Hall, CMC 340 E 9th St, Claremont, CA, United States

Consider rational polynomials in multiple variables that are linear with respect to some of the variables. In this talk we discuss the problem of finding a zero of such polynomials that are bounded with respect to a height function. For a system of such polynomials satisfying certain technical conditions we prove the existence of a […]

Mathematical model for HIV-1 infection with stem cell and immune-therapy (Prof. Noufe Aljahdaly, King Abdulaziz University / CGU)

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

Title: Mathematical model for HIV-1 infection with stem cell and immune-therapy Speaker: Noufe Aljahdaly, Department of Mathematics, King Abdulaziz University / CGU Abstract: The AIDS is a chronic disease. Its most common treatment is the antiretroviral therapy (cART) and the virus can be more effected if the patients stop using cART. The other problem is […]

Applied Math Seminar: Michael Perlmutter (UCLA)

Claremont, CA, United States

Title:Geometric Scattering on Measure Spaces Abstract: Geometric Deep Learning is an emerging field of research that aims to extend the success of convolutional neural networks (CNNs) to data with non-Euclidean geometric structure. Despitebeing in its relative infancy, this field has already found great success in many applications such as recommender systems, computer graphics, and traffic […]

Watch your step: Modeling on Time Scales (Prof. Raegan Higgins, Texas Tech University)

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

Title: Watch your step: Modeling on Time Scales Speaker: Raegan Higgins, Department of Mathematics & Statistics, Texas Tech University Abstract: Generally, differential and difference equations are used in the mathematical modeling of physical systems. Our modeling approach uses dynamic equations on time scales. A time scale T is an arbitrary, nonempty, closed subset of the […]

The Fell topology and the modular Gromov-Hausdorff propinquity (Jiahui Yu, Pomona College)

Roberts North 105, CMC 320 E. 9th St., Claremont, CA, United States

Given a unital AF (approximately finite-dimensional) algebra A equipped with a faithful tracial state, we equip each (norm-closed two-sided) ideal of A with a metrized quantum vector bundle structure, when canonically viewed as a module over A, in the sense of Latrémolière using previous work of Aguilar and Latrémolière. Moreover, we show that convergence of […]

GEMS March 4th Session

Harvey Mudd College at the Shanahan Teaching and Learning Center 301 Platt Blvd., Claremont, CA, United States

Sometimes Pi Equals 4 (Prof. Cornelia van Cott, University of San Francisco)

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

Title: Sometimes Pi Equals 4 Speaker: Cornelia van Cott, Department of Mathematics, University of San Francisco Abstract: Most of your mathematical life, you've known that pi is a number somewhere between 3.1 and 3.2. But if we exchange the usual notion of distance in two-dimensional space for others, pi can be any of an infinite number […]

Existence and uniqueness of minimizers in variational problems (Wilfrid Gangbo, UCLA)

Roberts North 105, CMC 320 E. 9th St., Claremont, CA, United States

We comment on the main steps to take when studying some variational problems. This includes optimization problems arising in geometry, machine learning, non linear elasticity, fluid mechanics, etc... For the sake of illustration, in this talk, we keep our focus on a minimization problem obtained after a time-discretization of the incompressible Navier-Stokes equations. Elementary geometric […]

Deniz Sarikaya on Narratives of Mathematical Practice (and why they matter!)

Claremont, CA, United States

Deniz Sarikaya joining us from the Technical University of Denmark and speaking on "Narratives of Mathematical Practice (and why they matter!)" (abstract below).   The speaker will join via zoom, but there will be a live audience on the second floor of Pitzer College's Gold Student Center in the Multipurpose room (in the building marked 3 here: https://www.pitzer.edu/about/maps-directions/quick-reference-map/).
