Numerical Analysis Seminar: Structure-preserving time integration methods based on relaxation by Hendrik Ranocha

Tid: 2023-02-07 15:15 till 16:30 Seminarium

Abstract.

Relaxation methods are small modifications of standard time integration schemes such as Runge-Kutta or linear multistep methods - designed to preserve the conservation or dissipation of important functionals of the solution. This can be an entropy in the case of compressible fluid flows, the energy of Hamiltonian problems, or another nonlinear invariant. We will introduce the basic idea, applications including dispersive wave equations, and provide an outlook to some recent developments.
