Abstract

We prove that the finitely presentable subgroups of residually free groups are separable and that the subgroups of type $\mathrm{FP}_\infty$ are virtual retracts. We describe a uniform solution to the membership problem for finitely presentable subgroups of residually free groups.

Left and right zero subsemigroups and an elementary approach to the Rees-Sushkevich Theorem

In a semigroup $S$ with idempotent $e$, the set of all elements $a$ of $S$ such that $ae=a$ and $ea=e$ forms the maximum left zero subsemigroup of $S$ containing $e$, and the set of all elements $b$ of $S$ such that $be=e$ and $eb=b$ forms the maximum right zero subsemigroup of $S$ containing $e$. We use these maximal right and left zero subsemigroups along with the maximal subgroups of a semigroup in the determination of maximal right and left subgroups, rectangular band subsemigroups, completely simple subsemigroups, rectangular subgroups, and completely $0$-simple subsemigroups. An elementary approach of the Rees-Sushkevich Theorem follows. Then we define rectangular $0$-bands and rectangular $0$-groups as completely $0$-simple analogues of rectangular bands and rectangular groups.

On a theorem of Artin and the dimension of the space spanned by the rational valued characters of a group

In this paper, we sharpen a theorem of Artin to show that for a finite group, the dimension of the subspace of class functions spanned by the rational valued characters equals the number of conjugacy classes of cyclic subgroups.

Common overlattices in trees and trees with fins

Bass and Kulkarni proved that any pair of free uniform lattices in the automorphism group of a tree have conjugates that both lie inside a third uniform lattice (which is not necessarily free). We show that this does not generalise to trees with fins. The construction of our counter-example involves working with a certain generalisation of the universal groups of Burger and Mozes.
