ON EMBEDDING CERTAIN GROUPS INTO GROUPS ACTING ON TREES WITH INVERSIONS
In this paper we show that if G is a group acting on a tree X with inversions, then every subfundamental domain (T; Y) induces a group H and a tree denoted XH on which H acts with inversions such that H is embedded in G and XH is embedded in X. We apply the result to tree product of groups and to a new class of groups called quasi HNN groups.
