摘要:
In this talk, we consider the numerical solution of the KdV type equations with rough initial data. The rough data makes the solution nonsmooth, which causes accuracy order reduction or nonconvergence problem for classical discretizations. To overcome the problem, a class of low-regularity integrators will be introduced for the KdV, mKdV and gKdV models. The proposed methods can offer the optimal convergence rate in time with less regularity assumption on the solution than usual.
