8 Bounded Perturbations of Nonselfadjoint Operators,nvertibility conditions and bounds for the spectra of such operators. In particular, we consider perturbations of the von Neumann - Schatten operators and operators with von Neumann - Schatten Hermitian components.

3 Invertibility of Finite Matrices,The present chapter deals with various types of invertibility conditions for finite matrices. In particular, we improve the classical Levy-Desplanques theorem and other well-known invertibility results for matrices that are close to triangular ones.
