Compactness conditions for the spectrum of ordered pairs of linear operators (English)
0 references
Certain questions of the general spectral theory of ordered pairs of linear operators acting from one Banach space to another are studied. Necessary and sufficient conditions of the point at infinity isolation in the extended spectrum of ordered pairs of linear operators are given.
