Hawking radiation and Hawking flux from spherical reduction

General Relativity and Quantum Cosmology 2007-05-23 v1

Abstract

Using heat kernel techniques we show that the relation between Hawking temperature and radiation flux known from Einstein gravity in D dimensions can be reproduced from the spherically reduced action. A recent controversy regarding the D=2 anomaly for that case is discussed. The generalized effective Polyakov action in the presence of a dilaton field is presented.
