To introduce metric and topological spaces and to extend some theorems about convergence and continuity in the case of sequences of real numbers and real-valued functions of one real variable.
This course generalizes some theorems about convergence and continuity of functions from the Level 4 unit Analysis 1, and develops a theory of convergence and uniform convergence and in any metric space. Topics will include basic topology (open, closed, compact, connected sets), continuity of functions, completeness, the contraction mapping theorem and applications, compactness and connectedness.
Relation to other units
This unit is a member of a sequence of analysis units at levels 5, 6 and 7. It is a prerequisite for Measure Theory & Integration, Advanced Topics in Analysis, and Functional Analysis.
At the end of the course the student should know and understand the definitions and theorems (and their proofs) and should be able to use the ideas of the course in unseen situations.
Metric spaces (definition, examples, open sets, closed sets, interior, closure, limit points, equivalent metrics, product metrics).
Completeness (limits, continuity, Cauchy sequence, complete sets, isometries, completion of a metric space, contraction mapping theorem, existence and uniqueness of ordinary differential equations).
Compactness (definition, examples, continuous functions, uniform continuity, Heine-Borel theorem, Arzela- Ascoli theorem).
Connectedness (definition, examples, Rn, components, continuous functions, path connectedness).
Introduction to point set topology.
