Continuous complementors on B∗-algebras

Pak-Ken Wong

Vol. 33 (1970), No. 1, 255–260
Abstract

This paper is concerned with continuous and uniformly continuous complementors on a B-algebra. Let A be a B-algebra with a complementor p and Ep the set of all p-projections of A. We show that if A has no minimal left ideals of dimension less than three, then p is uniformly continuous if and only if Ep is a closed and bounded subset of A. We also give a characterization of the boundedness of Ep.
