Speaker: Leandro Vendramin, Free University of Brussels (VUB)
Title: An introduction to Nichols algebras
Abstract
Nichols algebras appear in various areas of mathematics, ranging from
Hopf algebras and quantum groups to Schubert calculus and conformal
field theory. Originally introduced in the 1970s through the work of
Nichols, they have been rediscovered multiple times, maybe because
they appear in several different contexts. In this introductory talk,
I will review the basic concepts and outline the main challenges
involved in classifying Nichols algebras over groups. In particular, I
will discuss some recent classification theorems, highlighting a
result obtained in collaboration with Andruskiewitsch and Heckenberger
concerning finite-dimension.
