Where: SMRI Seminar Room (Macleay Building A12 Room 301) [ROOM CHANGE DUE TO BOARD TALK] 

Title: Hochschild cohomology of flag varieties 

Abstract: Originating in the study of associative algebras, Hochschild cohomology of a
projective variety captures a generalized deformation theory of the variety and has a
rich underlying algebraic structure.  For the case of flag varieties, this cohomology
theory also carries an interesting representation structure for the corresponding
group--although unlike other cohomology theories, very little is known at large.  In
this talk, we'll introduce some key features of Hochschild cohomology and its
relationship to representation theory and a conjecture of Kostant.
