DESCRIPTION:Title: <a href="https://researchseminars.org/talk/notts_ag/44/
 ">Hochschild cohomology of partial flag varieties and Fano 3-folds</a>\nby
  Pieter Belmans (Bonn) as part of Online Nottingham algebraic geometry sem
 inar\n\n\nAbstract\nThe Hochschild-Kostant-Rosenberg decomposition gives a
  description of the Hochschild cohomology of a smooth projective variety i
 n terms of the sheaf cohomology of exterior powers of the tangent bundle. 
 In all but a few cases it is a non-trivial task to compute this decomposit
 ion\, and understand the extra algebraic structure which exists on Hochsch
 ild cohomology. I will give a general introduction to Hochschild cohomolog
 y and this decomposition\, and explain what it looks like for partial flag
  varieties (joint work with Maxim Smirnov) and Fano 3-folds (joint work wi
 th Enrico Fatighenti and Fabio Tanturri).\n
