Abstract

Let MM be a closed surface, q2q\geq 2 and n2n\geq 2. In this paper, we analyze the Coxeter-type quotient group Bn(M)(q)B_n(M)(q) of the surface braid group Bn(M)B_{n}(M) by the normal closure of the element σ1q\sigma_1^q, where σ1\sigma_1 is the classic Artin generator of the Artin braid group BnB_n. Also, we study the Coxeter-type quotient groups obtained by taking the quotient of Bn(M)B_n(M) by the commutator subgroup of the respective pure braid group [Pn(M),Pn(M)][P_n(M),P_n(M)] and adding the relation σ1q=1\sigma_1^q=1, when MM is a closed orientable surface or the disk.
