"Improved" traceless stress tensors are then constructed;each violates one of the above criteria.However,when d=N+2,there is a duality equivalence between N-form models and massless scalars.Here we show that conformal invariance is not lost,by constructing a quasilocal gauge invariant improved stress tensor.The correlators of the scalar theory are then reproduced,including the latter's trace anomaly.8 pages ,CERN-TH.7224 IAS 94/24High Energy Physics - TheoryGeneral Relativity and Quantum Cosmologytext
