DESCRIPTION:Title: <a href="https://researchseminars.org/talk/WiSe/24/">Wh
 at is (non-equivariant) elliptic cohomology?</a>\nby Matthew Spong (The Un
 iversity of Queensland) as part of What is ...? Seminar\n\n\nAbstract\nIn 
 this talk we will begin with a sketch of what elliptic cohomology is reall
 y about. Thus we will introduce the concept of a genus\, which is an invar
 iant of manifolds which are equipped with extra structure\, and from there
  we will define an elliptic genus. We then aim to briefly describe the rol
 e of elliptic genera in elliptic cohomology\, and to sketch the relationsh
 ip to index theory on free loop spaces. If time permits\, we will finally 
 describe a version of elliptic cohomology which was constructed in terms o
 f the K-theory of free loop spaces by Kitchloo and Morava.\n
