Phys. Rev. D 64, 047701 (2001) [4 pages]Simplified method for trace anomaly calculations in d<~6Received 2 May 2001; published 6 July 2001 We discuss a simplified method for computing trace anomalies in dimensions d<~6. It is known that in the quantum mechanical approach trace anomalies in d dimensions are given by a (d/2+1)-loop computation in an auxiliary 1D sigma model with arbitrary geometry. We show how one can obtain the same information using a simpler (d/2)-loop calculation on an arbitrary geometry supplemented by a (d/2+1)-loop calculation on the simplified geometry of a maximally symmetric space. © 2001 The American Physical Society URL:
