摘要: We construct and analyze combinations of rational implicit explicit multistep methods for nonlinear evolution equations extend thus recent results concerning the discretization parabolic equations. The resulting schemes are linearly include as particular cases implicit–explicit well combination Runge–Kutta extrapolation. establish optimal order error estimates. abstract applied to a third–order equation arising in modelling flow fluidized bed. discretize this space by Petrov–Galerkin method. fully discrete require solving some linear systems advance time with coefficient matrices same all levels.
