DESCRIPTION:Title: <a href="https://researchseminars.org/talk/cats2021/20/
 ">Intersections and sums in exact categories</a>\nby Aran Tattar as part o
 f Additive categories between algebra and functional analysis\n\n\nAbstrac
 t\nWe discuss ways to generalise the intersections and sums of subobjects 
 to exact categories (from abelian categories). One way leads to new charac
 terisations of quasi-abelian and abelian categories\; another allows us to
  study the Jordan-Hoelder property for exact categories and describe cases
  when this property is satisfied. \n\nBased on joint work with T. Brüstle
  and S. Hassoun\n
