Adian Groups and Pregroups,aper we give a geometric argument, using diagrams, to prove a result, due basically to O. A. Sarkisian, which says: If n > 1, and q. ∈ Q for i = 1,…,n, and if 1 = q.?q.…q. is true in G, the there exists i such that q.?q. ∈ Q. This gives a set of examples of a concept invented by Baer. related to pre

Dendrology of Groups: An Introduction,ections of this theory with hyperbolic geometry and with W. Thurston’s theory of measured laminations. The picture has been developed further by the above-mentioned people and also by H. Bass, M. Bestvina, M. Culler, H. Gillet, M. Gromov, W. Parry, F. Rimlinger and J. Stallings, among others.

Definitions and preliminary discussions,dard example of such a V is obtained as follows. Fix a finite presentation of Γ and let P be the 2-dimensional cell complex whose 1-cells correspond in the usual way to the generators and the 2-cells to the relations in Γ, such that π.(P) = Γ. Then embed P into ?. and take a regular neighborhood of P ? ?. for V.
