Aroca–Cumplido finite-presentation conjecture for labeled braided Higman–Thompson groups

About 5 years old · traced to

Let d≥2d\geq 2 and r≥1r\geq 1, let BdB_d be the braid group with dd strings, and let H≤BdH\leq B_d be a finitely presented subgroup. The group bVd,r(H)bV_{d,r}(H) is the labeled braided Higman–Thompson group associated with these data. Aroca–Cumplido's conjecture. For all d≥2d\geq 2 and r≥1r\geq 1, the group bVd,r(H)bV_{d,r}(H) is finitely presented when HH is finitely presented. This conjecture concerns finite presentability in the family of labeled braided Higman–Thompson groups; the paper confirms related finiteness results, but the supplied text does not state that this particular conjecture has been resolved.
