MiS Preprint Repository

We have decided to discontinue the publication of preprints on our preprint server as of 1 March 2024. The publication culture within mathematics has changed so much due to the rise of repositories such as ArXiV (www.arxiv.org) that we are encouraging all institute members to make their preprints available there. An institute's repository in its previous form is, therefore, unnecessary. The preprints published to date will remain available here, but we will not add any new preprints here.

On the $\Gamma$-Convergence of Discrete Dynamics and Variational Integrators

Stefan Müller and Michael Ortiz

Abstract

For a simple class of Lagrangians and variational integrators, derived by time discretization of the action functional, we supply conditions ensuring: i) The $\Gamma$-convergence of the discrete action sum to the action functional; ii) The weak$^*$ convergence of the discrete trajectories in $W^{1,\infty}({\mathbb{R}})$ and uniform convergence on compact subsets; and iii) The convergence of the Fourier transform of the discrete trajectories as measures in the flat norm.
