活动内容摘要:

We establish two-sided heat kernel estimates for full time and space of the Schr\odinger operator $-\frac{1}{2}\Delta+V$ on $\R^d$, where the potential $V(x)$ is locally bounded and behaves like $c|x|^{-\alpha}$ near infinity for some $\alpha\in (0,2)$ with $c> 0$, or for some $\alpha>0$ with large $c<0$. In particular, the potential $V$ is decaying near infinity but does not necessarily belong to the so-called Kato-class.
