Essential normality of some classes of operators in tensor products of Hilbert spaces

Abstract

We establish general criteria for the domains of definition of spectral integrals to be essential. On the basis of these criteria, we prove that some classes of operators are essentially normal in tensor products of Hilbert spaces.
