Simultaneous unitary equivalence to Carleman operators with arbitrarily smooth kernels

Igor M. Novitskii

In this paper, we describe families of those bounded linear operators on a separable Hilbert space that are simultaneously unitarily equivalent to integral operators on L2​(R) wi…

Integral representations of closed operators as bi-Carleman operators with arbitrarily smooth kernels

Igor M. Novitskii

In this paper, we characterize all closed linear operators in a separable Hilbert space which are unitarily equivalent to an integral bi-Carleman operator in L2​(R) with bounded…
