报告摘要
We consider the Korteveg de Vries (KdV) equation on the real line and study the problem of the invariance of white noise measure under the flow. This problem has previously been studied on the torus by Oh, Quastel, and Valkó. In the real line case, additional difficulty arises due to the fact that white noise fails to belong to H-1 (the optimal space for well-posedness of KdV). To overcome this, we pass through a sequence of suitable Hamiltonian approximations that are closely connected to the complete integrability of KdV. This is joint work with R. Killip and M. Visan.
