On the Absolutely Continuous Subspace for Non - Selfadjoint Operators
The paper is devoted to the problem of absolutely continuous and singular subspaces of non – selfadjoint operators defined as pseudo–Friedrichs extensions of operators of the form with the natural domain dom , where , , , , and , , are self–adjoint operators such that and are relatively bounded …
