Introduction to Poncelet porisms, Darboux grids, and integrable billiards

Le colloquium reprend mardi 12 octobre 2021 à 16h30 dans l'amphi Lebesgue.

Abstract. The Poncelet theorem is one of the most beautiful results from projective geometry. Despite its long history, it again and again re-appears and reincarnates
connecting various fields of mathematics. We will review a wreath of topics from classical to modern ones.
