摘要

Let m, m', r, r', t, t' be positive integers with r, r' ' 2. Let Lr denote the ring that is universal with an invertible 1×r matrix. Let Mm(L_r~(?t)) denote the ring of m × m matrices over the tensor product of t copies of Lr. In a natural way, Mm(L_r~(?t)) is a partially ordered ring with involution. Let PU_m(L_r~(?t)) denote the group of positive unitary elements. We show that PU_m(L_r~(?t)) is isomorphic to the Brin-Higman-Thompson group tV_(r,m); the case t=1 was found by Pardo, that is, PU_m(Lr) is isomorphic to the Higman-Thompson group V_(r,m). We survey arguments of Abrams, ánh, Bleak, Brin, Higman, Lanoue, Pardo and Thompson that prove that t'V_(r',m') ~= tV_(r,m) if and only if r' =r, t' =t and gcd(m', r'-1) = gcd(m, r-1) (if and only if Mm'(L_(r')~(?t')) and M_m(L_r~(?t)) are isomorphic as partially ordered rings with involution).
