報告摘要:The KdV hierarchy is a hierarchy of integrable equations generalizing the KdV equation. Using the modified Muria transform, we first relate it to the Gardner hierarchy, and by exploiting the idea of approximate flow, we show that the whole hierarchy is wellposed for initial data in H1 on the line. We also prove results in the periodic case.  This is based on joint work with H.Koch and F. Klaus.
