DESCRIPTION:Title: <a href="https://researchseminars.org/talk/GDS/8/">Open
  r-spin intersection theory</a>\nby Ran Tessler (Weizmann Institute of Sci
 ence) as part of Geometry and Dynamics seminar\n\n\nAbstract\nIn 1992 Witt
 en conjectured that the intersection theory on the moduli \nof r-spin curv
 es gives rise to a Gelfand Dickey tau function\, and \nproved his conjectu
 re in genus 0.\nRecently\, in a joint work with Buryak and Clader we made 
 a similar \nconjecture/construction in the open setting:\nWe conjectured t
 hat intersection theory on the moduli of r-spin \nsurfaces with boundaries
  should give rise to the Gelfand Dickey *wave* \nfunction and proved it in
  genus 0. In my talk I will describe all this\, \nin particular\, I'll exp
 lain what is an r-spin structure\, what is the \nGelfand-Dickey hierarchy 
 and what is the motivation. If time permits\, \na mirror theorem (based on
  work with Gross and Kelly) will also be shown.\n
