摘要：
We study the finiteness properties of the braided Higman-Thompson group bV(d,r)(H) with labels in H <= B-d, and bF(d,r)(H) and bT(d,r)(H) with labels in H <= PBd, where B-d is the braid group with d strings and PBd is its pure braid subgroup. We show that for all d >= 2 and r >= 1, the group bV(d,r)(H) (resp. bT(d,r)(H) or bF(d,r)(H) is of type F-n if and only if H is. Our result in particular confirms a recent conjecture of Aroca and Cumplido.
