On joint spectra of families of unbounded operators
A. R. Mirotin Francisk Skorina Gomel State University
Abstract:
We consider several types of joint spectra of a finite set of commuting
closed operators in a Banach space. We establish new relations between
these spectra (it was previously known only that the Taylor spectrum
is contained in the commutant spectrum) and prove spectral mapping theorems
in the case of generators of semigroups. Some of these theorems generalize
previous results of the author. The results obtained are applied to
stability issues for multi-parameter semigroups.
Keywords:
unbounded operator, joint spectrum, Bernstein function, Bochner–Philips functional calculus, spectral mapping theorem, multi-parameter operator semigroup, uniform stability, strong stability, abstract Cauchy problem.
