## Miscellaneous

My notes (fr) for the seminar "Geometry of groups, symplectic and contact geometries",
organised by Camille Horbez and Anne Vaugon.
Some notes (fr), titled "Billards, tours de Young et paires standards", written for the workshop
in ergodic theory at the university of Orsay. They are a short and technical introduction to hyperbolic billiards, to some tools used in their study (Young towers and standard pairs), and to some applications of
averaging methods to billiards. I presented a second talk on the averaging methods themselves, following the excellent introduction by Jacopo de Simoi and Carlangelo Liverani.
My PhD dissertation, "Théorèmes limites pour les sommes de Birkhoff de fonctions de moyenne nulle en théorie ergodique en mesure infinie", defended on December 10th, 2013 (fr).
A Beamer (fr) for the lecture on "Volumes mixtes et théorème d'Hadwiger", Journées Louis Antoine on convexity, Rennes, April 5th, 2012.
