Computation of endo-fixed closures in free-abelian times free groups
Mallika Roy, Enric Ventura
In this paper, we explore the behaviour of the fixed subgroups of endomorphisms of free-abelian times free (FATF) groups. We exhibit an algorithm which, given a finitely generated…
The central tree property and algorithmic problems on subgroups of free groups
Mallika Roy, Enric Ventura, Pascal Weil
We study the average case complexity of the uniform membership problem for subgroups of free groups, and we show that it is orders of magnitude smaller than the worst case complexi…
A list of applications of Stallings automata
Jordi Delgado, Enric Ventura
This survey is intended to be a fast (and reasonably updated) reference for the theory of Stallings automata and its applications to the study of subgroups of the free group, with…
Intersection configurations in free and free times free-abelian groups
Jordi Delgado, Mallika Roy, Enric Ventura
In this paper we study intersection configurations -- which describe the behaviour of multiple (finite) intersections of subgroups with respect to finite generability -- in the rea…
Relative order and spectrum in free and related groups
Jordi Delgado, Enric Ventura, Alexander Zakharov
In this paper, we consider a natural generalization of the concept of order of an element in a group: an element is said to have order in a subgroup of (\resp…
Onto extensions of free groups
Sebastià Mijares, Enric Ventura
An extension of subgroups of the free group of rank is called onto when, for every ambient free basis , the Stallings graph $Γ_{A…
