【 摘 要 】

We review a modification of the gravitational anomalies method for the calculation of Hawking-like radiation from horizons of n-dimensional static or stationary spacetimes with horizon(s). This modification uses (i) the chirality near the horizon and (ii) the principle of effective theory of gravity, in order to resolve some of its defects and apply it to spacetimes with constant curvature. The new approach can be smoothly applied in the same class of spacetime as the original gravitational anomalies method.
