Talk Title: "Making sense of the Generalized Entropy of Gauss-Bonnet Gravity"

Abstract: 

Recently Lewkowycz and Maldacena have given a partial derivation of the Ryu-Takayanagi conjecture by developing a technique for performing the replica trick holographically.  Subsequent attempts to apply this technique to higher curvature theories of gravity were partly successful but also produces several puzzles.  In this talk I will present a resolution to the problem of so-called "sub-leading divergences" for perturbative Gauss-Bonnet gravity and discuss a related proposal for relaxing the assumption of replica symmetry in Lewkowycz and Maldacena's original derivation.
