A class of Discontinuous Galerkin methods for nonlinear variational problems

Georgios Grekas, Konstantinos Koumatos, Charalambos Makridakis +1

In the context of Discontinuous Galerkin methods, we study approximations of nonlinear variational problems associated with convex energies. We propose element-wise nonconforming f…

Convergence of Discontinuous Galerkin Methods for Quasiconvex and Relaxed Variational Problems

Georgios Grekas, Konstantinos Koumatos, Charalambos Makridakis +1

In this work, we establish that discontinuous Galerkin methods are capable of producing reliable approximations for a broad class of nonlinear variational problems. In particular,…
