OVERVIEW

The course offers an introduction to General Topology.

AIMS AND CONTENT

LEARNING OUTCOMES

The course aims to introduce the student to the foundations of General Topology, with particular attention to the concepts of continuity, connectedness and compactness.

AIMS AND LEARNING OUTCOMES

At the end of the course, students will have a good understanding of the fundamental notions of General Topology, such as continuity, separation axioms, connectedness, compactness, metrizability.

PREREQUISITES

The courses of the first year of our Laurea in Matematica.

TEACHING METHODS

Traditional method: lectures in presence.
