Query: Hawking radiation and Hawking flux from spherical reduction   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.
