1. ELEMENTS OF GENERAL TOPOLOGY: topological spaces, neighbourhoods, closure,
interior, boundary. Basis and subbasis, topology generated by a family of subsets, subspaces, the product of two topological spaces. Convergence and continuity, Heine's theorem, sequential characterization of the closure. The separation axioms (T1 and T2). The topology of metric and semimetric spaces, completeness. Compact, sequentially compact, and precompact spaces, Hausdorff's theorem. Connected spaces, normal spaces and Tietze's theorem. 2. MEASURE THEORY: Algebras and sigma-algebras. Abstract measure, sigma-additivity. Exterior measures, measurable sets with respect to exterior measures, Caratheodory's theorem. The Lebesgue measure in Euclidean spaces, regular measures. 3. LEBESGUE INTEGRAL: Measurable and simple functions, arithmetic operations and limits, the approximation theorem. The construction of the Lebesgue integral. The monotone convergence theorem and the dominated convergence theorem. Application in calculus (integrals with parameters). Relation with the Riemann integral (proper and improper). |
