The extremal length systole is defined as the infimum of the extremal lengths of all non-contractible closed curves. I will dis cuss joint work with Didac Martinez-Granado and Franco Vargas Pallete in w hich we compute the extremal length systole of the Bolza surface\, the mos t symmetric surface of genus two. The calculation involves certain identit ies for elliptic integrals called the Landen transformations. We also prov e that the Bolza surface is a local maximizer for the extremal length syst ole and conjecture that it is the unique global maximizer. \n\n\n \n DTSTART:20211112T193000Z DTEND:20211112T203000Z SUMMARY:Maxime Fortier Bourque (Universite de Montreal) URL:/mathstat/channels/event/maxime-fortier-bourque-un iversite-de-montreal-334494 END:VEVENT END:VCALENDAR
