Numerical methods for the Rosenau equation. (English) Zbl 1021.65048
Summary: A continuous in time finite element Galerkin method is first discussed for a Korteweg-de Vries-like Rosenau equation in several space variables and optimal error estimates in $$L^2$$, $$H^1$$ as well as in $$H^2$$-norms are derived for conforming $$C^1$$-finite element spaces. Finally, several fully discrete schemes like backward Euler, Crank-Nicolson and two step backward methods are proposed and related convergence results are established.
