Abstract

This research explores various properties of topological spaces, including compactness, Lindelöf, separability and countability. We emphasize the inter-relations among these properties. For example, we show that a compact space is Lindelöf, and that second countability implies the Lindelöf property and separability. For implications that are not true, we provide counter-examples. Metrizable topological spaces are called metric spaces, in which more properties may be studied. Boundedness, total boundedness, and completeness are such examples. Consequently, there are, in our opinion, more interesting inter-relations and implications we can discuss. As a highlight of this thesis, we show that, in metric space, compactness is equivalent to total boundedness and completeness. We also provide a counter-example that shows that boundedness and completeness do not imply compactness.
