Abstract: Burgers equation with initial boundary value problems were presented, and the approximation scheme of implicit-explicit multistep finite element methods were proposed. Theoerical analysis shows that the scheme yield the approximate solutions with optimal accuracy.
Key words: Burgers equations; implicit-explicit multistep finite element methods; optimal order error estimates
