Abstract

In this paper and a sequel, we study a group which is the quotient of a free oduct of groups by the normal closure of a single word that is contained in a subgroup which has the form of a free product of two cyclic groups.

We use known properties of generalised triangle groups, together with detailed analysis of pictures and of words in free monoids, to prove a number of results such as a Freiheitssatz and the existence of Mayer-Vietoris sequences for such groups under suitable hypotheses. The results eneralise those in an earlier article of the second author and Shwartz
