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.
