Abstract
Summary: ``In the context of gravitational theories describingrenormalization group flows across dimensions via AdS/CFT, we study therole of higher-derivative corrections to Einstein gravity. We use theNull Energy Condition to derive monotonicity properties of candidateholographic central charges formed by combinations of metric functions.We also implement an entropic approach to the characterization of thefour-derivative flows using the Jacobson-Myers functional anddemonstrate, under reasonable conditions, monotonicity of certain termsin the entanglement entropy via the appropriate generalization of theRyu-Takayanagi prescription. In particular, we show that any flow froma higher dimensional theory to a holographic $\rm CFT_2$ satisfies atype of monotonicity. We also uncover direct relations betweenNEC-motivated and entropic central charges.''
