摘要：

Energy-momentum tensors are investigated for the renormalizable noncommutative Grosse and Wulkenhaar scalar field theory. In the massless situation, the ordinary trick for recovering a traceless tensor reveals to be inefficient. However, a locally conserved non-symmetric energy-momentum tensor is provided making use of algebraic techniques. Broken dilatation symmetry is also discussed. (C) 2007 Elsevier B.V.
