Comparison of Variations of Statistical and Wald's Entropies

Abstract

We write the variation of the statistical entropy of matter fields outside a black hole along a Killing vector. This is done for generalized theories of gravity, using a Lie derivative and identification of the energy momentum tensor.

This paper has been withdrawn by the authors due to an error that led to incorrect conclusions
