Sufficient conditions for the root-class residuality of certain generalized free products
E. V. Sokolov, E. A. Tumanova Ivanovo State University, Ivanovo, Russia
Abstract:
Given a class $\mathscr K$ of groups, we prove that the free product of a $\mathscr K$-group $A$ and a residually $\mathscr K$-group $B$ with amalgamated subgroup which is a retract of $B$ is a residually $\mathscr K$-group. We also obtain a sufficient condition for the root-class residuality of a generalized free product of two residually $\mathscr K$-groups with amalgamated subgroup which is a retract of one of the factors.
Keywords:
root class, residual $\pi$-finiteness, root-class residuality, generalized free product.
