Department Colloquiums & Events

Mathematics Colloquium/ Special Lecture, UCR Interdisciplinary Center for Quantitative Modeling in Biology
June 01, 2022 @ 12:00 pm
Zoom
Spatial Ecology & Singularly Perturbed Reaction-Diffusion Equations Prof. Arjen Doelman, Mathematisch Instituut, Lorentz Center; Leiden University, The Netherlands Abstract: Pattern formation in ecological systems is driven by counteracting feedback mechanisms on widely different spatial scales. Moreover, ecosystem models…
The Block Distinguished Lecture: M. Susan Montgomery, USC
May 25, 2022 @ 3:30 pm
Skye 284
M. Susan Montgomery, USC Orthogonal representations: from groups to Hopd algebras to tensor categories Let G be a finite group and V a finite dimensional representation of G over the complex numbers. According to a wonderful theorem of Frobenius and Schur from 1906, there are only three possibilities for V: V has a…
Positive Curvature and Discrete Abelian Symmetries
May 18, 2022 @ 12:00 pm
Skye Hall 268
Catherine Searle, Wichita State University Positively curved manifolds are notoriously hard to classify. In the early 90's, based on the observation that the few known examples are all highly symmetric, Karsten Grove proposed his "Symmetry Program" which suggests trying to classify such manifolds with the additional hypothesis of…
Burton Jones Lecture & Conference
May 11, 2022 @ 4:00 pm
May 11th - Skye Hall 284 May 14th - Olmstead 1208
Burton Jones Lecture Information: Bill Goldman, University of Maryland May 11th - Skye Hall 284 Classification of Geometric Structures on Manifolds In 1872 F. Klein, based on ideas of S. Lie, proposed that the classical geometries be understood via the theory of transformation groups and homogeneous spaces. Later in the…
CLL: Supporting STEM Learning by Leveraging and Bolstering Spatial Skills: A Method of Diversifying STEM
May 06, 2022 @ 9:00 am
Zoom
Dr. Kinnari Atit, School of Education, University of California at Riverside   In the U.S., there is a disparity between the number of students pursuing STEM and the number of professionals needed to meet global and economic demands. Of those that do pursue STEM, few are women or individuals from underrepresented minority…
Gravitational instantons and the Hitchin equations
April 27, 2022 @ 4:00 pm
Skye 284
Dr. Rafe Mazzeo, Stanford Gravitational instantons are some of the simplest Riemannian manifolds with special holonomy: they are noncompact, Ricci flat, hyperkähler four-manifolds. There is now a scheme for classifying all of them which is well underway. Many of these spaces arise as moduli spaces of solutions to certain gauge-…
CLL-A New Mathematics Gateway Seminar
April 15, 2022 @ 9:00 am
Zoom
Challenges and Advantages of a Principle-Based Calculus Course Speaker: Dr. David Weisbart, Department of Mathematics, University of California at Riverside Abstract: We will discuss what it means for a course to be principle-based and describe an underlying philosophy of teaching and learning that supports principle-based…
Relaxed Energies, Defect measures and Minimal Currents
February 16, 2022 @ 4:00 pm
Zoom
Fanghua Lin, Courant Institute, NYU Energy minimizing harmonic maps from a three-ball into the two-sphere are well understood. A natural existence question for a continuous harmonic map with a suitably given Dirichlet boundary value or in a given homotopic class [a problem that I learned from R.Schoen in mid-80s] remains open.  …
