Heat Kernel Expansion and Extremal Kerr-Newmann Black Hole Entropy in
Einstein-Maxwell Theory
   [PDF]

Sayantani Bhattacharyya, Binata Panda, Ashoke Sen
We compute the second Seely-DeWitt coefficient of the kinetic operator of the metric and gauge fields in Einstein-Maxwell theory in an arbitrary background field configuration. We then use this result to compute the logarithmic correction to the entropy of an extremal Kerr-Newmann black hole.
