Title

What is a quantum group?

Abstract

In this talk I will explain what a quantum group (Hopf algebra) is, but from a slightly nonstandard point of view that focuses on their actions on other algebras. The main objective is to then discuss actions of quantum groups on singular plane curves that turn the latter into quantum homogeneous spaces.

Based on joint work with Angela Tabiri, Manuel Martins, and Blessing Oni.
