摘要：

We study the superspace formulation of the noncommutative nonlinear supersymmetric O(N) invariant sigma-model in 2 + 1 dimensions. We prove that the model is renormalizable to all orders of I IN and explicitly verify that the model is asymptotically free. (C) 2001 Elsevier Science B.V. All rights reserved.
