Title: Classical applications of consistent discretizations
Abstract: We discuss two models in which the "consistent discretizations" approach is used to provide discrete models that approximate continuum situations of interest, as one does in numerical relativity. The first model is a mechanical system that nevertheless is challenging given the global structure of phase space. The second model are the single polarized Gowdy cosmologies. We will show that one can use the consistent discretizations as good numerical approximations with convergence and stability.
