  • Linear Multifractional Stable Sheets in the Broad Sense: Existence and Joint Continuity of Local Times (Qidi Peng, Institute of Mathematical Sciences, CGU)

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

    We introduce the notion of linear multifractional stable sheets in the broad sense (LMSS) to include both linear multifractional Brownian sheets and linear multifractional stable sheets. The purpose of the framework is to study the existence and joint continuity of the local times of LMSS, and also the local Holder condition of the local times […]

  • 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 […]

  • 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 […]

  • 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 […]

  • 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 […]
