Conjugator length in finitely presented groups
Martin R. Bridson, Timothy R. Riley, Andrew W. Sale
The conjugator length function of a finitely generated group gives the minimal upper bound on the length of a conjugator for a pair of words that represent conjugate elements i…
Conjugacy in a family of free-by-cyclic groups
Martin R. Bridson, Timothy R. Riley, Andrew W. Sale
We analyse the geometry and complexity of the conjugacy problem in a family of free-by-cyclic groups where the defining free-group automorphism is positi…
On virtual indicability and property (T) for outer automorphism groups of RAAGs
Andrew Sale
We give a condition on the defining graph of a right-angled Artin group which implies its automorphism group is virtually indicable, that is, it has a finite-index subgroup that ad…
Calculating the virtual cohomological dimension of the automorphism group of a RAAG
Matthew B. Day, Andrew W. Sale, Richard D. Wade
We describe an algorithm to find the virtual cohomological dimension of the automorphism group of a right-angled Artin group. The algorithm works in the relative setting; in partic…
Outer automorphism groups of graph products: subgroups and quotients
Andrew Sale, Tim Susse
We show that the outer automorphism groups of graph products of finitely generated abelian groups satisfy the Tits alternative, are residually finite, their so-called Torelli subgr…
Outer automorphism groups of right-angled Coxeter groups are either large or virtually abelian
Andrew Sale, Tim Susse
We generalise the notion of a separating intersection of links (SIL) to give necessary and sufficient criteria on the defining graph of a right-angled Coxeter group so th…
