【Abstract】 The characteristic finit;clement and finite difference methods (finite element and finite difference methods are combined with the method of char-apteiistics ) to 1-periodic initial-value problem for the Korteweg-de Vries equation are analysed.Optimal order error estimates are obtained for both method更多还原
