Learning outcomes

At the end of the course the student acquires the knowledge of geometric and topological tools that could be used to construct mathematical models. The student knows some examples that could be involved in applications.

Course contents

Introduction to quivers, quiver representations, and path algebra associated with.

Reflection functors, Gabriel theorem, classification of quivers into finite type/Euclidean/wild.

Quiver varieties, GIT quotients, Kac theorems and finite fields.

Application to flag varieties, to Hilbert scheme, and to persistent homology (topological data analysis).
