DESCRIPTION:Title: <a href="https://researchseminars.org/talk/PHK-cohomolo
 gy-seminar/138/">An introduction to Nichols algebras</a>\nby Leandro Vendr
 amin (Vrije Universiteit Brussel (VUB)) as part of Prague-Hradec Kralove s
 eminar Cohomology in algebra\, geometry\, physics and statistics\n\nLectur
 e held in ZOOM meeting.\n\nAbstract\nNichols algebras appear in various ar
 eas of mathematics\, ranging from \nHopf algebras and quantum groups to Sc
 hubert calculus and conformal \nfield theory. Originally introduced in the
  1970s through the work of \nNichols\, they have been rediscovered multipl
 e times\, maybe because \nthey appear in several different contexts. In th
 is introductory talk\, \nI will review the basic concepts and outline the 
 main challenges \ninvolved in classifying Nichols algebras over groups. In
  particular\, I \nwill discuss some recent classification theorems\, highl
 ighting a \nresult obtained in collaboration with Andruskiewitsch and Heck
 enberger \nconcerning finite-dimension.\n
