## Abstract We study the situation when the automorphism group of a recursively saturated structure acts on an โโtree. The cases of (โ, <) and models of Peano Arithmetic are central in the paper. (ยฉ 2003 WILEYโVCH Verlag GmbH & Co. KGaA, Weinheim)

## Abstract The purpose of this paper is to generalize Yalรงin's result [Trans. Amer. Math. Soc. **352**, 2689โ2700 (2000)] from tori to solvmanifolds. As a result, we prove that if (โค~__p__~)^__r__^ acts freely on a solvmanifold __M__ of dimension __n__, then __r__ โค __n__ (ยฉ 2010 WILEYโVCH Verlag
A new extension of the major index, defined in terms of Coxeter elements, is introduced. For the classical Weyl groups of type B, it is equidistributed with length. For more general wreath products it appears in an explicit formula for the Hilbert series of the (diagonal action) invariant algebra.
## Abstract This paper explores the connection between homeomorphisms of the unit circle, codimensionโ1 measured laminations on closed surfaces, and free actions of surface groups on IRโtrees.
