In this project we are going to explore the “Countable Topological Spaces” in greater details. We shall try to understand how these axioms are affected to spaces, by taking open and closed sets. A clear idea of the separation properties typical of the spaces we are studying helps us understand what kind of proof techniques to use. When working with T1- Spaces, we use that points are closed. In particular, the inverse image of (via a continuous function) of a points in a T1- Spaces is a closed sets. Finally we conclude that an Axiom of Countability is a properties of certain mathematical objects that requires the existence of a countable set with certain properties, while without it such sets might not exists.
