The relationship between fragmentable spaces and class $\mathcal {L}$ spaces

The Relationship between Different Separation Notions on L-topological Spaces

In the present paper we study the smooth topology and its equivalentL-topology, the corresponding L-continuous, L-open, and homeomorphism maps.We also study the concept of several separation axioms (like ST◦, ST1, ST2, andtheir strong and weak forms on the mentioned topology). Finally we investigatesome of their properties and the relations between them.MSC 2010. 39B72, 47H0...

On the Relationship between Filter Spaces and Weak Limit Spaces

Countably based filter spaces have been suggested in the 1970’s as a model for recursion theory on higher types. Weak limit spaces with a countable base are known to be the class of spaces which can be handled by the Type-2 Model of Effectivity (TTE). We prove that the category of countably based proper filter spaces is equivalent to the category of countably based weak limit spaces. This resul...

On the Relationship between Filter Spaces and Equilogical Spaces

It was already known that the category of T 0 topological spaces is not itself cartesian closed, but can be embedded into the cartesian closed categories FIL of lter spaces and EQU of equilogical spaces where the latter embeds into the cartesian closed category ASSM of assemblies over algebraic lattices. Here, we rst clarify the notion of lter space|there are at least three versions FIL a FIL b...

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...
