On certain function spaces and group structures

compactifications and function spaces on weighted semigruops

chapter one is devoted to a moderate discussion on preliminaries, according to our requirements. chapter two which is based on our work in (24) is devoted introducting weighted semigroups (s, w), and studying some famous function spaces on them, especially the relations between go (s, w) and other function speces are invesigated. in fact this chapter is a complement to (32). one of the main fea...

On the dual of certain locally convex function spaces

In this paper, we first introduce some function spaces, with certain locally convex topologies, closely  related to the space of real-valued continuous functions on $X$,  where $X$ is a $C$-distinguished topological space. Then, we show that their dual spaces can be identified in a natural way with certain spaces of Radon measures.

Representability of Certain Function Spaces

LetCp(X) be the space of all continuous real-valued functions on a space X , with the topology of pointwise convergence. In this paper we show thatCp(X) is not domain representable unless X is discrete for a class of spaces that includes all pseudo-radial spaces and all generalized ordered spaces. This is a first step toward our conjecture that if X is completely regular, then Cp(X) is domain r...

Compact and strictly singular operators on certain function spaces

On Topological and Linear Homeomorphisms of Certain Function Spaces

Let X be a countable metric space which is not locally compact. We prove that the function space C,,(X) is homeomorphic to rr,, We also give examples of countable metric spaces X and Y which are not locally compact and such that C,,(X) and C,,(Y) are not linearly homeomorphic.
