DESCRIPTION:Title: <a href="https://researchseminars.org/talk/LAGOON/64/">
 Euler structures and noncommutative volume forms</a>\nby Pavel Safronov (U
 niversity of Edinburgh\, UK) as part of Longitudinal Algebra and Geometry 
 Open ONline Seminar (LAGOON)\n\n\nAbstract\nCalabi-Yau structures on dg ca
 tegories provide a noncommutative analog of symplectic structures. In this
  talk I will introduce a noncommutative analog of volume forms called nonc
 ommutative Euler structures. I will give some examples of these and relate
  noncommutative Euler structures to string topology-type operations. An ap
 plication of these ideas is the proof that the Goresky--Hingston string co
 product on the homology of free loop space is not homotopy invariant. If I
  have time\, I will also discuss how Euler structures give rise to volume 
 forms on derived mapping stacks. This is a report on work in progress join
 t with Florian Naef.\n\nZOOM Meeting Link\nhttps://icms-org-uk.zoom.us/j/8
