The clack of billiard balls could be heard from the next door room. There is a full-size billiard table in one of the downstairs rooms.

Two such billiard tables will be called geodesically equivalent if they are geodesically equivalent in the complement of the union of the corresponding singular sets. A slab of freshwater ice formed the smooth top of a billiard table made of ice blocks, with pockets and cushions crafted out of walrus-hide. In the case of geodesically equivalent billiard tables, these integrals are pairwise commuting. Whenever the billiard particle enters the hole, it gets absorbed with its orbit deleted from the phase space. Another class of integrable billiard tables appears on quadrics. It is weaker in that a uniformly distributed billiard path is always dense, but not conversely. In [6], it is shown that the topological entropy of a compact non-degenerate semi-dispersing billiard on any manifold of non-positive sectional curvature is finite. In this paper we show that the topological entropy of a compact non-degenerate semidispersing billiard on any manifold of non-positive sectional curvature is finite. That theory is already applicable for billiard systems, too. Thus, we obtained that any cylindric billiard with one-dimensional generators is necessarily tight, unless all generators are parallel. The connected configuration space of a so-called cylindric billiard system is a flat torus minus finitely many spherical cylinders. The transformation in question is a projective billiard transformation, the transversals being the normals to in the metric under consideration. The billiard transformation is defined in metric terms (equal angles), and, in particular, it is not equivariant under projective transformations of the plane. An example of this situation is given by the usual billiard in an ellipse; the billiard transformation has an invariant area form.
