Derek W. Robinson, Adam Sikora · Studia Mathematica · 2011
Let $\Omega$ be an open subset of ${\mathbb R}^d$ with $0\in \Omega$. Furthermore, let $H_\Omega=-\sum^d_{i,j=1}\partial_ic_{ij}\partial_j$ be a second-order partial differential operator with domain $C_c^\infty(\Omega)$ where the coefficients $c_{ij}\i
