Preserving operators on semiprime f-algebras

Functional Analysis 2021-08-17 v1

Abstract

It is an open problem whether a separating operator acting between semiprime f-algebras is a weighted composition operator ( <cite>AAB</cite>). We prove that the answer is positive if and only if the separating operator is almost contractive. As a consequence, we can generalized and strengthen some well-known results on separating operators.
