Abstract

We study the convergence of higher order schemes for the Cauchy problem associated to the KdV equation. More precisely, we design a Galerkin type implicit scheme which has higher order accuracy in space and first order accuracy in time. The convergence is established for initial data in L2, and we show that the scheme converges strongly in L2(0,T; L2loc(\R)) to a weak solution. Finally, the convergence is illustrated by several examples.
