Crank-Nicolson finite difference scheme for the Rosenau-Burgers equation. (English) Zbl 1166.65041
The authors consider an initial-boundary value problem of Rosenau-Burgers equation $$u_{t}+u_{xxxxt}-u_{xx}+u_{x}+uu_{x}=0$$ and propose a Crank-Nicolson type finite difference scheme. The existence and uniqueness of numerical solutions are derived. It is proved that the finite difference scheme is stable and convergent in the order of $ O(\Delta t^{2}+\Delta x^{2})$. The method is tested by an example. It will be better if the new scheme is tested by a shock wave problem.
