Heat kernel bounds for elliptic partial differential operators in divergence form with Robin-type boundary conditions II

Fritz Gesztesy, Marius Mitrea, Roger Nichols +1

The principal aim of this short note is to extend a recent result on Gaussian heat kernel bounds for self-adjoint $L^2(\Om; d^n x)$-realizations, $n \in N$ , $n \geq 2$ , of divergen…

On square root domains for non-self-adjoint Sturm-Liouville operators

Fritz Gesztesy, Steve Hofmann, Roger Nichols

We determine square root domains for non-self-adjoint Sturm--Liouville operators of the type $L_{p, q, r, s} = - \frac{d}{d x} p \frac{d}{d x} + r \frac{d}{d x} - \frac{d}{d x} s + q$ in $L^2((…
