In my talk I will describe all this\, \nin particular\, I 'll explain what is an r-spin structure\, what is the \nGelfand-Dickey hie rarchy and what is the motivation. If time permits\, \na mirror theorem (b ased on work with Gross and Kelly) will also be shown.\n LOCATION:https://stable.researchseminars.org/talk/GDS/8/ END:VEVENT END:VCALENDAR
