Title: One-relator products of locally indicable groups
Abstract: A group is said to be locally indicable if each of its
non-trivial, finitely generated subgroups admits an epimorphism onto the
inifite cyclic group. A one-relator product is the quotient of a free
product of groups by the normal closure of a single element (not
conjugate into one of thre free factors). Much of the rich theory of
one-relator groups can be generalised to one-relator products of locally
indicable groups. In this talk I will survey some older results in this
area, present some more recent joint results with Hamish Short, and
discuss some open questions.
