Advancements is Spectral Variational Integrators
James Hall
UCSD
Abstract:
Last spring, we presented Spectral Variational Integrators, a class of variational integrators that had both excellent conservation properties and exhibited geometric convergence. This talk will present extensions to this work, including Spectral Variational Integrators on lie groups, pseudospectral variational integration of the one dimensional wave equation, and several conjectures about the behavior of Spectral Variational Integrators based on observations of numerical examples.
