The restricted thr ee-body problem is invariant under various antisymplectic involutions. The se real structures give rise to the notion of symmetric periodic orbits wh ich simultaneously have a closed string interpretation namely as a periodi c orbit as well as an open string interpretation as Hamiltonian chords. Th is makes the bifurcation analysis of symmetric periodic orbits very intrig uing since under bifurcations two local Floer homologies are invariant\, t he periodic one as well as the Lagrangian one. In this talk we explain how methods from symmetric space theory can help to extract efficiently datas from reduced monodromy matrices of periodic orbits helping to analyse the possible bifurcation patterns. \n\n \n\nZoom link: https://theias.zoom.us /j/97116147750?pwd=L2Fud1Y4Z2xsT3dhU2NrV0ZXd3lUQT09 (Meeting ID: 971 1614 7750 \; Passcode: 816898)\n\n \n DTSTART:20211210T141500Z DTEND:20211210T154500Z SUMMARY:Urs Frauenfelder (Augsburg) URL:/mathstat/channels/event/urs-frauenfelder-augsburg -335391 END:VEVENT END:VCALENDAR
