Trace anomaly on a quantum spacetime manifold
PHYSICAL REVIEW D, no. 8 (2006)
Abstract
In this paper we investigate the trace anomaly in a space-time where single events are delocalized as a consequence of short distance quantum coordinate fluctuations. We obtain a modified form of heat kernel asymptotic expansion which does not suffer from short distance divergences. Calculation of the trace anomaly is performed using an I...More
