Aula Seminari (Dipartimento di Matematica)

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.
