We consider variational time integration using continuous Galerkin-Petrov methods applied to evolutionary systems of changing type. We prove optimal-order convergence of the error in a cGP-like norm and conclude the paper with some numerical examples and conclusions.
Keywords: evolutionary equations, changing type system, continuous Galerkin-Petrov, space-time approach
