Entropies in QFT Feng Xu, UCR Abstract: I will give an introduction to relative entropies in Quantum Field Theory, and discuss their connections to subfactor theory.
Bio-Inspired Locomotion Across Scales Using Artificial Intelligence
June 03, 2025 @ 2:00 pm
Zoom Only
Sina Heydari, Santa Clara University Abstract: Biological organisms exhibit remarkable proficiency in locomotion. From sea stars walking on rocky and uneven terrains to microscopic organisms swimming through viscous fluids, they are well-adapted to their environments. Effective motion in such environments requires the ability to…
Topological Dynamics of Knotted and Tangled Matter
May 19, 2025 @ 11:00 am
Skye 268
Dr. Vishal Patil, UCSD Topology and adaptivity play fundamental roles in controlling the dynamics of biological and physical systems, from chromosomal DNA and biofilms to cilia carpets and worm collectives. How topological rules give rise to adaptive, self-optimizing dynamics in soft and living matter remains poorly understood.…
Integral equations with nonlocal operators: applications and recent development

Computing high dimensional Wasserstein geometric flows in neural network parameter space Haomin Zhou, Georgia Tech Machine learning based strategies have impacted computational mathematics significantly in recent years. Many used-to-be intractable tasks such as solving high dimensional PDEs or computing solution operators for…
Affine geometry and the Auslander Conjecture
April 23, 2025 @ 4:00 pm
Skye 284
Jeff Danciger, University of Texas at Austin The Auslander Conjecture is an analogue of Bieberbach’s theory of Euclidean crystallographic groups in the setting of affine geometry.  It predicts that a complete affine manifold (a manifold equipped with a complete torsion-free flat affine connection) which is compact must have…
The Distinguished Burton Jones Lecture - Dr. Renato Bettiol
March 14, 2025 @ 4:00 pm
Skye 284
Dr. Renato Bettiol, Lehman College Minimal surfaces in elongated ellipsoids Imagine stretching an n-dimensional ellipsoid inside Euclidean space so that one of its semiaxes becomes very large. This causes a corresponding stretching of geometric objects that locally minimize length (geodesics) or area (minimal surfaces) inside…
An invitation to Anosov representations
March 12, 2025 @ 4:00 pm
Skye 284
Dick Canary, University of Michigan Abstract: Fuchsian groups arise naturally as groups of covering transformations of hyperbolic surfaces. One may view them as images of discrete faithful representation of free groups and surface groups into PSL(2,R). The study of hyperbolic surfaces and deformation spaces of Fuchsian groups is…
