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.

16 Hille - Tamarkin Integral Operators,e inverse operators and positive invertibility conditions are established. In addition, bounds for the spectral radius are suggested. Applications to nonselfadjoint differential operators and integro-differential ones are also discussed.

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.
