Connectedness, are considered in Sect. .. As we will see later, it is important for some purposes that the space satisfy one of the two connectedness conditions locally. Localized versions of both conditions are formulated and studied in Sect. ..

Separation Axioms, disjoint nbds. For spaces satisfying this axiom, we shall prove several important theorems of topology such as Urysohn’s Lemma, Tietze Extension Theorem, and Urysohn Metrization Theorem. The other axiom is stronger than .-axiom and weaker than .-axiom for most of the spaces. This requires separatio

Covering Spaces,the base point is defined and it is applied to prove the Borsuk–Ulam theorem for .. The next three sections mainly concern with the problem of classification of covering spaces of a locally path-connected space. In Sect. ., we define the notion of equivalence for covering spaces of a given space and
