Applied Math Colloquium - Jeremy Hoskins

Jan. 24, 2020

Jeremy Hoskins, Department of Mathematics, Yale University Elliptic PDEs on regions with corners Many of the boundary value problems frequently encountered in the simulation of physical problems (electrostatics, wave propagation, fluid dynamics in small devices, etc.) can be solved by reformulating them as boundary integral equations. This approach reduces the...

Nonlinear Waves Seminar - Nalini Joshi

Jan. 21, 2020

Nalini Joshi, Department of Mathematics, Sydney University When Applied Mathematics Collided with Algebra Imagine walking from one tile to another on a lattice defined by reflections associated with an affine Coxeter or Weyl group. Examples include triangular or hexagonal lattices on the plane. Recently, it was discovered that translations on...

Stats, Optimization, and Machine Learning Seminar - Zhihui Zhu

Jan. 21, 2020

Zhihui Zhu, Department of Electrical and Computer Engineering, University of Denver Provable Nonsmooth Nonconvex Approaches for Low-Dimensional Models As technological advances in fields such as the Internet, medicine, finance, and remote sensing have produced larger and more complex data sets, we are faced with the challenge of efficiently and effectively...

Applied Math Colloquium - Dan Larremore

Jan. 17, 2020

Dan Larremore, Department of Computer Science, University of Colorado Boulder Complex Networks, Math, and Malaria: From Evolution to Epidemiology Progress in the global battle for malaria elimination has flatlined since 2015, with the single-cell P. falciparum parasite killing one child for every minute of the year. Some of this plateau...

Nonlinear Waves Seminar - Justin Cole

Dec. 10, 2019

Justin Cole, Department of Applied Mathematics, University of Colorado Boulder Soliton Dynamics in the Korteweg-de Vries Equation with Nonzero Boundary Conditions Inspired by recent experiments, the Korteweg-de Vries equation with nonzero Dirichlet boundary conditions is considered. Two types of boundary data are examined: step up (which generates a rarefaction wave)...

Stats, Optimization, and Machine Learning Seminar - Amir Ajalloeian, Maddela Avinash, Ayoub Ghriss

Dec. 10, 2019

Amir Ajalloeian; Department of Electrical, Computer, and Energy Engineering; University of Colorado Boulder Inexact Online Proximal-gradient Method for Time-varying Convex Optimization This paper considers an online proximal-gradient method to track the minimizers of a composite convex function that may continuously evolve over time. The online proximal-gradient method is "inexact,'' in...

Math Bio Seminar - Dan Messenger

Dec. 10, 2019

Dan Messenger, Department of Applied Mathematics, University of Colorado Boulder Aggregation-Diffusion Phenomena in Domains with Boundaries This talk relates to a class of mathematical models for the collective behaviour of autonomous agents, or particles, in general spatial domains, where particles exhibit pair-wise interactions and may be subject to environmental forces...
