The Resonance Theorem for Subspaces
E. I. Berezhnoi P. G. Demidov Yaroslavl State University
Abstract:
Under some additional assumptions on an unbounded sequence of operators and the geometry of the spaces, it is shown that, in the classical Banach–Steinhaus resonance theorem, the set of divergence contains an infinite-dimensional space, excluding zero.
Keywords:
Banach–Steinhaus resonance theorem, Banach space, Banach couple, linear operator, set of divergence, Hahn–Banach theorem.
