In the second half we will investigate the topological pr operties of the Frobenius pullback. In particular\, we will establish that it is a continuous and open map. This will lead to a new perspective on p revious results of ours on rigid flat connections. This\n\nis joint work w ith Hélène Esnault.\n\nIn person at UQAM PK-5675\n\nor online at Zoom meet ing 86352363947\n\nhttps://can01.safelinks.protection.outlook.com/?url=htt ps%3A%2F%2Fuqam.zoom.us%2Fj%2F86352363947&data=05%7C02%7Cjackie.castreje%4 0mcgill.ca%7Cd6e5c38028c74e6f334c08dc15da735b%7Ccd31967152e74a68afa9fcf8f8 9f09ea%7C0%7C0%7C638409275181472880%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLj AwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C3000%7C%7C%7C&sdata =cNQV4OSDQJOtwWxrlI4Sr%2FvqeWJxYDs0pxwhLRhIJ9Y%3D&reserved=0\n DTSTART:20240117T183000Z DTEND:20240117T193000Z SUMMARY:Michael Groechenig (University of Toronto) URL:/mathstat/channels/event/michael-groechenig-univer sity-toronto-354277 END:VEVENT END:VCALENDAR
