- Course objectives
- The course presents one of the basic disciplines of modern mathematics. Introduces topological spaces which naturally generalize the well-known concepts of a metric space and a continuous function. Presents the separation axioms, the concepts of connectedness and compactness. Explains the concept of homotopy and introduces the fundamental group including its use. Finally, it presents uniform spaces and uniformly continuous functions.
- Learning outcomes
- Understanding the concept of continuity formalized by means of topological and uniform spaces;
grasping the concepts of separation, connectedness and compactness;
ability to see the topological background of the theory of continuous real-valued functions and metric spaces;
familiarity with the concept of homotopy, including the fundamental group and its use for proving Brouwer's fix-point theorem and the fundamental theorem of algebra. - Syllabus
