Structure-preserving time discretization: lessons for numerical relativity?

Presented by:

Venue: 
INI Seminar Room 1
Abstract: 
In numerical ODEs, there is a rich literature on methods that preserve certain geometric structures arising in physical systems, such as Hamiltonian/symplectic structure, symmetries, and conservation laws. I will give an introduction to these methods and discuss recent work extending some of these ideas to numerical PDEs in classical field theory.
