DESCRIPTION:Title: <a href="https://researchseminars.org/talk/LAGOON/13/">
 A cup-cap duality in Koszul calculus</a>\nby Andrea Solotar (University of
  Buenos Aires\, Argentina) as part of Longitudinal Algebra and Geometry Op
 en ONline Seminar (LAGOON)\n\n\nAbstract\nIn this talk I will introduce a 
 cup-cap duality in the Koszul calculus of N-homogeneous algebras following
  https://arxiv.org/abs/2007.00627. As an application of this duality\, it 
 follows that the graded symmetry of the Koszul cap product is a consequenc
 e of the graded commutativity of the Koszul cup product. I will also comme
 nt on a conceptual approach to this problem that may lead to a proof of th
 e graded commutativity\, based on derived categories in the framework of D
 G algebras and DG bimodules. This is joint work with Roland Berger.\n
