HiePACS Working Group

Osni Marques will give a presentation: Friday 24/11 at 14:00 in Grace Hopper 2. Title: Nonlinear Eigensolver based on Padé Approximants Abstract: In this presentation, we discuss a strategy for finding nontrivial solutions (λ,x) for a class of nonlinear eigenvalue problems of the form F( λ)x = 0. Specifically, we focus on problems related to …
