Abstract

We study the problem of strong uniqueness in L2 for the Dirichlet operator perturbed by a singular complex-valued potential. We reveal sufficient conditions on the logarithmic derivative ß of the measure pdx and the potential q, which ensure that the operator \((\Delta + \beta \cdot\nabla - q) \upharpoonright C_0 ^\infty (\mathbb{R}^d ) \) has a unique extension generating a C0-semigroup on L2. The method of a-priori estimates of solutions of the corresponding elliptic equations is employed.
