A nonsupersymmetric matrix orbifold

We construct the matrix description for a twisted version of the IIA string theory on S-1 with fermions antiperiodic around a spatial circle. The resu lt is a 2 + 1-dimensional U(N) x U(N) nonsupersymmetric Yang-Mills theory w ith fermionic matter transforming in the (N, (N) over bar). The the two U(N )'s are exchanged if one goes around a twisted circle of the worldvolume. R elations with type-0 theories are explored and we find type-0 matrix string limits of our gauge theory. We argue however that most of these results ar e falsified by the absence of SUSY nonrenormalization theorems and that the models do not in fact have a sensible Lorentz invariant space time interpr etation.
