## Abstract We study the situation when the automorphism group of a recursively saturated structure acts on an ββtree. The cases of (β, <) and models of Peano Arithmetic are central in the paper. (Β© 2003 WILEYβVCH Verlag GmbH & Co. KGaA, Weinheim)
Let A be the automorphism group of the one-rooted regular binary tree T and 2 G the subgroup of A consisting of those automorphisms admitting a ''finite Ε½ . description'' in their action on T . Let N G be the normaliser of G in A, let 2 A Ε½ . Ε½ . Aut G be the group of automorphisms of G, and let End
Associated to the multiplicative group of a definite quaternion algebra over Q are two notions of automorphic forms. One is a complex-valued function on the idele group. The other, a p-adic-valued function on a p-adic ``upper half-plane,'' arises from considering differentials on a Mumford curve ass
