Hello everyone,
This Wednesday, we will have a surprise field trip to the chemistry building (HCI E 2 -- I have no idea where that is either) for a non-group-meeting group seminar, with a talk by Sandra Rankovic.
Your favorite organizer, who has no doubt been sorely missed in this new group meeting era,
--Fred

Abstract: Dynamical billiards represent the Hamiltonian idealization of the billiard game, and they appear as natural models in problems of optics, acoustics and classical mechanics. They are defined by a connected region in 2D space with the piecewise smooth boundary, and the point particles of non-zero radius confined to move inside this region. The particles move freely until encountering the boundary or the other particle, when they reflect specularly. We investigate the two-particle circular billiard and its chaotic properties, and attempt approximating it with a randomly perturbed one-particle billiard in the limit of small particle radius.
