Conjugacy in Houghton's groups / Antolin Pichel, Yago (University of Neuchâtel. Mathematics Department) ; Burillo Puig, Josep (Universitat Politècnica de Catalunya. Departament de Matemàtica Aplicada IV) ; Martino, Armando (University of Southampton. School of Mathematics)
Let n ∈ N. Houghton's group Hn is the group of permutations of {1, . . . , n} × N, that eventually act as a translation in each copy of N. We prove the solvability of the conjugacy problem and conjugator search problem for Hn, n ≥ 2.

Pure braid subgroups of braided Thompson's groups / Brady, Tom (Dublin City University. Department of Mathematics) ; Burillo Puig, Josep (Universitat Politècnica de Catalunya. Departament de Matemàtica Aplicada IV) ; Cleary, Sean (The City College of New York & The CUNY Graduate Center. Department of Mathematics) ; Stein, Melanie (Trinity College. Department of Mathematics)
We describe some properties of braided generalizations of Thompson's groups, introduced by Brin and Dehornoy. We give slightly different characterizations of the braided Thompson's groups BV and BVd which lead to natural presentations which emphasize one of their subgroup-containment properties. [...]

Quasi-Potency and Cyclic subgroup separability / Burillo Puig, Josep ; Martino, Armando ; Centre de Recerca Matemàtica
We study the profinite topology on discrete groups and in particular the property of cyclic subgroup separability. We investigate the class of quasi-potent, cyclic subgroup separable groups, producing many examples and showing how it behaves with respect to certain group constructions.

Combinatorial and metric properties of Thompson's group T / Burillo Puig, Josep ; Cleary, Sean ; Stein, Melanie ; Taback, Jennifer ; Centre de Recerca Matemàtica
We discuss metric and combinatorial properties of Thompson's group T, such as the normal forms for elements and uniqueness of tree pair diagrams. We relate these properties to those of Thompson's group F when possible, and highlight combinatorial differences between the two groups. [...]

Computational explorations in Thompson's group F / Burillo Puig, Josep ; Cleary, Sean ; Wiest, Bertold ; Centre de Recerca Matemàtica
Here we describe the results of some computational explorations in Thompson's group F. We describe experiments to estimate the cogrowth of F with respect to its standard finite generating set, designed to address the subtle and difficult question whether or not Thompson's group is amenable. [...]
