Spectral Analysis of Differential Operators with Unbounded Operator Coefficients in Weighted Spaces of Functions
M. S. Bichegkuev North-Ossetia State University, Vladikavkaz
Abstract:
The spectral properties of operators constructed from a family of evolution operators are studied in Banach spaces of vector functions defined by a weight function of pre-exponential growth. Necessary and sufficient conditions for the invertibility of such operators are obtained in terms of exponential dichotomy. We prove a spectrum mapping theorem for semigroups of Howland difference operators generated by the operator under study.
