Algebraic Topology, Master Degree, 6 cfu

Lectures: Prof. Gilberto Bini


This course aims at introducing some basic tools of Algebraic Topology, such as singular homology and cohomology and their relations. For these purposes, we will recall some fundamental topics, such as CW-complexes and homotopy theory. Time permitting, we will introduce persistent homology and go over some of its recent applications to various areas, such as biomedical engineering.
