Abstract

The h-p version of the continuous Petrov-Galerkin time steppingmethod is analyzed for nonlinear initial value problems. AnL-error bound explicit with respect to the localdiscretization and regularity parameters is derived. Numerical examples areprovided to illustrate the theoretical results.
