A geometric characterization of range-kernel complementarity

Functional Analysis 2023-03-27 v2

Abstract

We show that a bounded linear operator on a Banach space with closed range has range-kernel complementarity if and only if its generalized amplitude is less than π\pi. An application to the strong convergence of the iterations of a bounded linear operator is also given.
