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
