Mathematics Faculty Colloquium - Yangbo Ye

Thursday, May 8, 2025 3:30pm to 4:20pm

MacLean Hall

Title: Number theory and cryptography Abstract: In this presentation Professor Ye will survey his work and progress in number theory since his last colloquium talk in the department. Topics include the Riemann zeta function, automorphic L-functions, their functoriality, upper bounds, and zero statistics, computational number theory, and its applications to cyberspace security or insecurity. Short Bio: Professor Yangbo Ye is a professor of Mathematics with expertise in number theory and...

Math Colloquium - Speaker: Dr. Rob Falgout, Lawrence Livermore National Lab

MacLean Hall

Title: Parallel-in-Time Solution of Systems of Linear and Nonlinear Hyperbolic PDEs Abstract: The multigrid reduction in time (MGRIT) method is a parallel multigrid-in-time solver designed to be as non-intrusive as possible and take advantage of existing simulation codes and techniques. This has worked well for parabolic equations, but parallel-in-time methods for advection-dominated hyperbolic problems have proven difficult to develop. In previous work, we demonstrated the effectiveness of a...
