DESCRIPTION:Title: <a href="https://researchseminars.org/talk/TRAC/35/">Id
 empotent (co)algebras and generalizations of Hochschild cohomology</a>\nby
  Matt Hogancamp (Northeastern University) as part of The TRAC Seminar - Th
 éorie de Représentations et ses Applications et Connections\n\n\nAbstrac
 t\nIn this talk I will discuss the notion of an idempotent (co)algebra (or
  perhaps more descriptively\, idempotent *dg* (co)algebra).  The two-sided
  bar complex of an algebra gives an especially important class of examples
 \, but there is a plethora of other examples appearing throughout mathemat
 ics.  I will describe how the endomorphism algebra of an idempotent (co)al
 gebra naturally admits the structure of a Gerstenhaber algebra\, generaliz
 ing a well known structure on Hochschild cohomology.\n
