TRIPLE-PRODUCT-FREE SETS

Bulletin of the Australian Mathematical Society, 2023
AbstractIn this paper, we study triple-product-free sets, which are analogous to the widely studied concept of product-free sets. A nonempty subset S of a group G is triple-product-free if $abc \notin S$ for all $a, b, c \in S$ . If S is triple-product-free and is not a proper subset of any other triple-product-free set, we say that S is locally ...

Free Product Fixed Points

Journal of the London Mathematical Society, 1988
The principal result of the paper is a generalization of the well-known theorem of \textit{S. M. Gersten} [Adv. Math. 64, 51-85 (1987; Zbl 0616.20014)] that in a free group of finite rank, the fixed-point subgroup of an automorphism is also of finite rank.

Free Products and Free Products with Amalgamations

1982
In this chapter, we shall describe the emergence of two new ideas which had a profound influence on the development of combinatorial group theory. Their creation is associated with three names: O. Schreier, who appeared prominently in Chapter II.3, E. Artin (1898–1962), and A. G. Kurosh (1908–1971).

COMMUTATORS IN FREE PRODUCTS

International Journal of Algebra and Computation, 1995
Topological methods are used to show that for certain subgroups S of a free product F, if w∈S is a commutator in F, then w is a commutator in S.
