Homological torsion growth in non-normal chains of graphs of free groups
Dario Ascari, Jonathan Fruchter
Let be a hyperbolic group that splits as a graph of free groups with cyclic edge groups, and which is not isomorphic to a free product of free and surface groups. We show that…
An algorithm to recognize echelon subgroups of a free group
Dario Ascari
We provide an algorithm that, given a finite set of generators for a subgroup of a finitely generated free group , determines whether is echelon or not and, in case of a…
Ideals of equations for elements in a free group and context-free languages
Dario Ascari
Let be a finitely generated free group, and let be a finitely generated subgroup. An equation for an element with coefficients in is an element $w(x)\in H…
Ideals of equations for elements in a free group and Stallings folding
Dario Ascari
Let be a finitely generated free group and let be a finitely generated subgroup. Given an element , we study the ideal of equations for wi…
