Abstract
It is shown that the Ornstein–Uhlenbeck operator perturbed by a multipolar inverse square potential
with suitable domain generates a quasi-contractive and positive analytic \(C_{0}\)-semigroup on the weighted space \(L^{2}(\mathbb {R}^{N},d\mu )\), where \(d\mu =\exp (-\Phi (x))dx\), \(\Phi \in C^{2}(\mathbb {R}^{N}, \mathbb {R})\), \(G \in C^{1}(\mathbb {R}^{N},\mathbb {R}^{N})\), \(c>0\), and \(a_{1},\ldots , a_{n}\in \mathbb {R}^{N}\). The proofs are based on an \(L^{2}\)-weighted Hardy inequality and bilinear form techniques.
