Learning Outcomes

Learning outcomes

Topology is a powerful tool for research and expression in all branches of Mathematical Science. In the last few years, Topology has been increasingly used in the creation of mathematical models that serve research applied disciplines such as Economics, Meteorology, Insurance Mathematics, Epidemiology in Medicine, etc. The didactic approach here is to initially give the theory of metric spaces and then, as a mere reference, an introduction to General Topology. An in-depth study of Metric spaces, in addition to preparing the student to accept the abstract structures of General Topology, helps him to better understand the structure of the Euclidean space n, which is studied the same time in the Multi-Variable Infinitesimal Calculus. Topics which are covered are convergence, continuity, completeness, total boundness, compactness, separability and connectedness. These concepts, as well as the proofs of the related results, are given in such a way that, wherever possible, they can be easily and without major changes adapted toTopological Spaces.

General Competences

Analysis and synthesis of data and information Autonomous work Teamwork Working in an interdisciplinary environment Promoting creative and inductive thinking Promoting analytical and synthetic thinking Production of new research ideas.

Syllabus

Metric spaces, definition, examples, basic properties. Metrics in vector spaces induced by norms. Diameter of a set, distance of sets. Sequences in metric spaces, subsequences, convergence of sequences. Functions between metric spaces, continuous functions, characterization of continuity via sequences, uniform continuity of functions. Open balls, closed balls, interior, closed hull and boundary, accumulation points and derived set. The topology of a metric space, the concept of a topological space.
