摘要：
Our purpose is to solve numerically the nonlinear evolutionary problem called Rosenau-Burgers (RB) equation. First, we have derived error estimates of semidiscrete finite element method for the approximation of the Rosenau-Burgers problem. For a second-order accuracy in time, we propose the Galerkin-Crank-Nicolson fully discrete method. Second, a linearized difference scheme for the Rosenau-Burgers equation is considered. It is proved that the proposed difference scheme is uniquely solvable, and the method is shown to be second-order convergent both in time and space in maximum norm. Finally, some numerical experiments are given to demonstrate the validity and accuracy of our linearized difference scheme.
