Spectral theory of closed distributive operators
Angus E. Taylor · Acta Mathematica · 1951
1. Introduction.Let X be a complex Banach space, and Y a closed distributive operator with domain and range both in X.Let [X] denote the set of all continuous distributive (bounded linear) operators which map X into itself.This set IX] is a ring, and in fact an algebra.Next suppose that we have an algebra, related in some
