Abstract

We embed general solutions to 4D Einstein-Maxwell theory into N ≥ 2 supergravity and study quadratic fluctuations of the supergravity fields around the background. We compute one-loop quantum corrections for all fields and show that the c-anomaly vanishes for complete N=2 multiplets. Logarithmic corrections to the entropy of Kerr-Newman black holes are therefore universal and independent of black hole parameters.
