Characterization of sharp global Gaussian estimates for Schrödinger heat kernels
Abstract
We investigate when the fundamental solution of the Schrödinger equation $\partial_t=Δ+V$ posseses sharp Gaussian bounds global in space and time. We give a characterization for $V\leq 0$ and a sufficient condition for general $V$.
