DESCRIPTION:Title: <a href="https://researchseminars.org/talk/Geolis/17/">
 Lagrangian cobordism and Chow groups</a>\nby Nick Sheridan (University of 
 Edinburgh) as part of Geometria em Lisboa (IST)\n\n\nAbstract\nHomological
  mirror symmetry predicts an equivalence of categories\, between the Fukay
 a category of one space and the derived category of another. We can "decat
 egorify" by taking the Grothendieck group of these categories\, to get an 
 isomorphism of abelian groups. The first of these abelian groups is relate
 d\, by work of Biran-Cornea\, to the Lagrangian cobordism group\; the seco
 nd is related\, via the Chern character\, to the Chow group. I will define
  the Lagrangian cobordism and Chow groups (which is much easier than defin
 ing the categories). Then I will describe joint work with Ivan Smith in wh
 ich we try to compare them directly\, and find some interesting analogies.
