Holography in Einstein Gauss-Bonnet gravity

Abstract

We investigate a holographic relation between Einstein Gauss-Bonnet gravity in n dimensions and its dual field theory in (n - 1) dimensions. We briefly review the AdS/CFT correspondence for the entropy in n-dimensional Einstein gravity and consider its extension to the case of n-dimensional Einstein Gauss-Bonnet gravity. We show that there is a holo-graphic relation between the entropies of an Einstein Gauss-Bonnet black hole in the bulk and the corresponding radiation on the brane in the high temperature limit. In particular, we find that the Hubble entropy evaluated when the brane crosses the horizon coincides with the black hole entropy in the high temperature limit.
