"Automorphisms of projective varieties and potential density, II"

In the second talk, we'll discuss Skolem's method and the analytic arc theorem as a means of studying the action of the automorphism group on a variety.  If time remains, we'll apply this method to show that if X is a surface defined over a number field and X has an automorphism that does not preserve a non-constant fibration then there is a number field K such that the K-points of X are Zariski dense.
