Abstract

The main aim of this chapter is to determine when a space of the form C(K) for a compact space K is a dual space or a bidual space,either isometrically or isomorphically. However, we shall first discuss when two spaces C(K) and C(L) are isomorphic and when they are isometrically isomorphic. Some results come from rather elementary considerations, but some require more sophisticated background.
