General Kernel estimates of Schrödinger type operators with unbounded diffusion terms

Loredana Caso, Markus Kunze, Marianna Porfido +1

We prove first that the realization $A_{\min }$ of $A:=\mathrm{div}(Q\nabla )-V$ in $L^2({\mathbb{R}}^d)$ with unbounded coefficients generates a symmetric sub-Markovian and ultracontr…
