Title:Number of collisions of n balls on the infinite billiard table after Burago-Ferleger-Kononenko.
Seminar:MASS Colloquium
Speaker:Anton Petrunin, Penn State
Consider a system of n hard balls moving freely and colliding elastically in Euclidean space. We will give an upper bound for the number of collisions in such a system. The proof is a simple application of Alexandrov geometry. The talk is based on work of D. Burago, S Ferleger and A. Kononenko
