DESCRIPTION:Title: <a href="https://researchseminars.org/talk/CGP-MP/37/">
 Open r-spin theories with multiple boundary states</a>\nby Ran Tessler (We
 izmann Institute of Science) as part of IBS-CGP Mathematical Physics Semin
 ar\n\n\nAbstract\nIn his 92' work\, Witten has defined the r-spin intersec
 tion theory. This theory have found an open counterpart\, in genus 0\, in 
 a recent joint work with Buryak and Clader. In the closed and open setting
  there are (internal) marked points\, which are allowed to carry any twist
  from the set 0\,1\,...\,r-1\, and in the open setting there are also boun
 dary markings whose twist is restricted to be r-2. My talk will describe a
  new construction of genus=0 open r-spin theories\, which allows different
  collections of boundary states\, as well as the relations satisfied by th
 e resulting intersection numbers. If time permits I will also say a few wo
 rds on higher genus. Based on a joint work with Yizhen Zhao.\n
