Further information on descriptions Description: Aims & Learning Objectives:
This course is intended to develop the theory of metric spaces and the topology of Rn for students with both "pure" and "applied" interests.
Objectives: To provide a framework for further studies in Analysis and Topology. Topics useful in applied areas such as the Contraction Mapping Principle will be emphasized. Students will know the fundamental results listed in the syllabus and have an instinct for their utility in analysis and numerical analysis. They should be able to demonstrate an in-depth understanding of the subject.

Definition and examples of metric spaces. Convergence of sequences. Continuous maps and isometries. Sequential definition of continuity. Subspaces and product spaces. Complete metric spaces and the Contraction Mapping Principle. Sequential compactness, Bolzano-Weierstrass theorem and applications. Open and closed sets (with emphasis on Rn). Closure and interior of sets. Topological approach to continuity and compactness (with statement of Heine-Borel theorem). Equivalence of Compactness and sequential compactness in metric spaces. Connectedness and path-connectedness. Metric spaces of functions: C[0,1] is a complete metric space.
