Titre Hochschild cohomology with support and the Grothendieck construction
Date15/04/2013
Horaire14:00 à 15:00
RésumeIn this talk we explain how the functoriality properties of Hochschild cohomology are essentially determined by an underlying level of ``grading categories''. We describe some techniques for deconstructing Hochschild cohomology, based upon sheaf properties and arrow categories, and we relate this to a generalized Grothendieck construction.
