Conditions for invertibility and Hurwitz stability
A. I. Perov Voronezh State University, Voronezh, Russia
Abstract:
In a generalization of Fiedler's theorem, a block condition for the invertibility of an operator and an estimate for the operator matrix of the inverse operator are presented. A block condition for an operator to be Hurwitz is also given, which contains an estimate of the spectral abscissa of the operator.
Keywords:
Banach space, bounded linear operator, spectral abscissa, Lozinskii logarithmic norm, invertible operators and the block invertibility condition (Fiedler's theorem), Hurwitz operators and a block condition for Hurwitz stability.
