On the distribution of the free path length of the linear flow in a honeycomb
Florin P. Boca, Radu N. Gologan
Let be an integer. For each $\eps >0$ remove from the union of discs of radius $\eps$ centered at the integer lattice points , with $m\nequiv n\mod{\ell}…

The average length of a trajectory in a certain billiard in a flat two-torus
Florin P. Boca, Radu N. Gologan, Alexandru Zaharescu
We remove a small disc from the flat two-dimensional torus and consider a point-like particle that starts moving from the center of the disc with linear trajectory. We provide asym…
