DESCRIPTION:Title: <a href="https://researchseminars.org/talk/LAGOON/83/">
 On exact dg categories</a>\nby Xiaofa Chen (Université Paris Cité\, Fran
 ce) as part of Longitudinal Algebra and Geometry Open ONline Seminar (LAGO
 ON)\n\n\nAbstract\nIn this talk\, we propose a framework of dg enhancement
 s\, which we call exact dg categories\, for a certain class of extriangula
 ted categories\, which we call algebraic. The motivation comes from typica
 l examples like Yilin Wu’s Higgs categories and Haibo Jin’s categories
  of dg Cohen-Macaulay modules. We will present several results concerning 
 the dg nerve\, the dg derived category\, tensor products and functor dg ca
 tegories with exact target. We will conclude by computing the lattice of a
 ll exact structures on dg categories satisfying certain strong finiteness 
 conditions.\n\nMeeting Link\n\nhttps://uni-koeln.zoom.us/j/91875528987?pwd
