Abstract
The characteristic features of [T-mu nu] in the Boulware, Unruh and Hartle- Hawking states for a conformal massless scalar field propagating in the Sch warzschild space-time are obtained by means of effective actions deduced by the trace anomaly. The actions are made local by the introduction of auxil iary fields and boundary conditions are carefully imposed on them in order to select the different quantum states.
