Title:  First-order aspects of Coxeter groups


Abstract: We will talk about recent advancement on the model theory of Coxeter groups. We will focus in particular on affine Coxeter groups and on Droms right-angled Coxeter groups. These investigations lead to a general model-theoretic analysis of homogeneity and existence of prime models in semidirect products of free abelian groups of finite rank by a finite group. This is joint with R. Sklinos.
