This wide ranging but self-contained account of the spectral theory of non-self-adjoint linear operators is ideal for postgraduate students and researchers, and contains many illustrative examples and exercises. Fredholm theory, Hilbert-Schmidt and trace class operators are discussed, as are one-param...

In this section, we present a brief introduction to the theory of linear operators and their applicability to shape analysis; we also introduce general techniques for their discretization. 3.1 Basics of linear operators Let M be a smooth surface possibly with boundary ∂M, and let L2(M) be ...
摘要: In this talk, we provide a complete deion of the spectra of linear fractional composition operators acting on the growth space and Bloch space over the upper half plane. In addition, we also prove that the norm, essential norm, spectral radius and essential spectral radius of a composit...
EPs. For recent reviews, see refs.59,60,61,62,63,64. Despite these intense activities on the one hand, and the fact that the mathematics of non-self-adjoint operators is well developed on the other, some of the basic features of complex photonic structures that are pertinent to their ...

Harmonic analysis of causal operators and their spectral properties The definition and study of causal operators are based on the representation theory of group algebras. We study the structure of the spectra of causal oper... AG Baskakov,IA Krishtal - 《Functional Analysis & Its Applications》 被...
Moreover, we apply the obtained results to discuss the incidence of some perturbation results on the behavior of relative essential spectra of unbounded linear operators acting on Banach spaces. We conclude by characterizations of the relative Schechter's and approximate essential spectrum. 关键词: ...
