## Abstract This paper is concerned with emptyness of the essential spectrum, or equivalently compactness of the semigroup, for perturbations of self‐adjoint operators that are bounded below (on an __L__^2^‐space). For perturbations by a (nonnegative) potential we obtain a simple criterion for com
Suppose that \(X_{1}\) is the standard Brownian motion in \(R^{d}, d \geqslant 3\), that \(\rho \in H^{1}\left(R^{d}\right)\) is a bounded continuous function such that \(|\nabla \rho|^{2}\) belongs to the Kato class and \(\mu\) is a measure belonging to the Kato class. Let \(A_{t}^{[\rho]}\) be def
