Compactness: Definition, limit point compactness, sequential compactness, net and directed set, local compactness, Tychonoff theorem, Stone-Weierstrass theorem, Arzela-Ascoli theorem. Topological Groups: Definitions, examples, compactness and connectedness in matrix groups. Separation Axioms: Hausdorff, regular and normal spaces; Urysohn lemma and Tietze extension theorem; compactification. Metrizability: Urysohn metrization theorem. |
