Honda-Tate theory says that every abelian variety mod p is isogenous to the reduction of a CM abelian variety.We will discuss the analogous statement for isogeny classes on Shimura varieties, and explain what is conjectured and what is known.

We shall discuss billiard dynamics in convex billiard tables in R^n.

In particular, we will describe a "symplectic point of view" which can be used, for example, to study the length of the shortest periodic billiard trajectory.
