Periodic billiard orbits in right triangles II

Serge Troubetzkoy

Periodic billiard orbits are dense in the phase space of an irrational right triangle. A stronger pointwise density result is also proven.

Always Finite Entropy and Lyapunov exponents of two-dimensional cellular automata

Pierre Tisseur

Given a new definition for the entropy of a cellular automata acting on a two-dimensional space, we propose an inequality between the entropy of the shift on a two-dimensional latt…
