A Szegő condition for a multidimensional Schrödinger operator
The authors deal with a multidimensional Schrödinger operator in \(L^2(\mathbb{R}^d)\) and introduce a version of a Szegő condition. According o the opinion of the authors their condition seems to be comparable with the classical Szegő integrability only for small energies. The corresponding condition for large energies is much weaker than the expected one and cannot be obtained by the methods of this paper.
