# Trace Anomalies and the Hawking Effect

@article{Christensen1977TraceAA, title={Trace Anomalies and the Hawking Effect}, author={Steven M. Christensen and Stephen A. Fulling}, journal={Physical Review D}, year={1977}, volume={15}, pages={2088-2104} }

The general spherically symmetric, static solution of ∇νTμν = 0 in the exterior Schwarzschild metric is expressed in terms of two integration constants and two arbitrary functions, one of which is the trace of Tμν. One constant is the magnitude of Ttr at infinity, and the other is determined if the physically normalized components of Tμν are finite on the future horizon. The trace of the stress tensor of a conformally invariant quantum field theory may be nonzero (anomalous), but must be…
