Abstract

In this note we extend the results of [3] concerning subaddi-tive separating maps from A = C(X ) to B = C(Y), for compact Haus-dor spacesX and Y, to the case whereA and B are regular Banachfunction algebras (not necessarily unital) with A satisfying Ditkin’s con-dition. In particular we describe the general form of these maps and geta result on continuity of separating linear functionals.
