Query: Current Trends and Open Problems in Arithmetic Dynamics   Arithmetic dynamics is the study of number theoretic properties of dynamical
systems. A relatively new field, it draws inspiration partly from dynamical
analogues of theorems and conjectures in classical arithmetic geometry, and
partly from $p$-adic analogues of theorems and conjectures in classical complex
dynamics. In this article we survey some of the motivating problems and some of
the recent progress in the field of arithmetic dynamics.
