DESCRIPTION:Title: <a href="https://researchseminars.org/talk/DerSem/24/">
 Another visit to the Donaldson-Thomas theory of K3xE</a>\nby Georg Oberdie
 ck (University of Bonn) as part of Derived seminar\n\n\nAbstract\nIn this 
 talk we consider the (reduced) Donaldson-Thomas theory of the product of a
  K3 surface and an elliptic curve. In rank 1\, these invariants can be vie
 wed as enumerating algebraic curves and are known for fiber classes over t
 he elliptic curve (work of Pandharipande and Thomas)\, and for classes pri
 mitive over the K3 (work of Pixton\, Shen and myself). I will explain how 
 to extend these results to arbitrary curve classes. If time permits\, I wi
 ll also give an outlook on the higher rank case (work in progress).\n
