Aims of the course and learning skills

Acquisition of the basilar notions of General Topology; n particular the student has to understand the concepts of connection, compactness, and numerability properties of topological spaces. Ability to recognize in concrete cases the topological properties of a space, and the continuity of maps between spaces. Understanding of some basic concepts of Algebraic Topology: in particular omotopy, retraction, and basic techniques for the computation of the fundamental group of a space.
