Finite element methods for Hamiltonian PDEs

Presented by: 
Ari Stern Washington University in St. Louis
Date: 
Wednesday 14th August 2019 - 15:00 to 16:00
Venue: 
INI Seminar Room 2
Abstract: 
Hamiltonian ODEs satisfy a symplectic conservation law, and there are many advantages to using numerical integrators that preserves this structure. This talk will discuss how the canonical Hamiltonian structure, and its preservation by a numerical method, can be generalized to PDEs. I will also provide a basic introduction to the finite element method and, time permitting, discuss how some classic symplectic integrators can be understood from this point of view.
