DESCRIPTION:Title: <a href="https://researchseminars.org/talk/cats2021/23/
 ">Functors and subcategories of n-exangulated categories</a>\nby Johanne H
 augland (NTNU) as part of Additive categories between algebra and function
 al analysis\n\n\nAbstract\nHerschend\, Liu and Nakaoka introduced $n$-exan
 gulated categories as a higher dimensional analogue of extriangulated cate
 gories. Natural examples are given by $n$-exact and $(n+2)$-angulated cate
 gories in the sense of Jasso and Geiss–Keller–Oppermann. In this talk\
 , we give a brief introduction to $n$-exangulated categories and explain h
 ow we can understand their subcategories in terms of subgroups of the asso
 ciated Grothendieck group. We also discuss functors between such categorie
 s. This is based on joint work in progress with R. Bennett-Tennenhaus\, M.
  H. Sandøy and A. Shah.\n
