     Cohomology in algebra, geometry, physics and statistics




         Wednesday, 22 October 2025 - 13:30 to 14:30

         Place: Institute of Mathematics of ASCR, Žitná 25, Praha 1,  
ZOOM meeting




         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.
