 Subadditive separating maps between regular Banach function algebras Bull. Korean Math. Soc. 2007 Vol. 44, No. 4, 753-761 Published online December 1, 2007 Fereshteh Sady and Yousef Estaremi Tarbiat Modares University, Tarbiat Modares University Abstract : In this note we extend the results of \cite{BN2} concerning subadditive separating maps from $A=C(X)$ to $B=C(Y)$, for compact Hausdorff spaces $X$ and $Y$, to the case where $A$ and $B$ are regular Banach function algebras (not necessarily unital) with $A$ satisfying Ditkin's condition. In particular we describe the general form of these maps and get a result on continuity of separating linear functionals. Keywords : separating maps, regular Banach function algebras, Ditkin's condition, strongly pointwise subadditive map MSC numbers : Primary 46J10, Secondary 46E25 Downloads: Full-text PDF
