Titre  The unreasonable effectiveness of higherderivative supergravity in AdS4 holography 
Résumé  I will describe the fourderivative corrections to fourdimensional N=2 minimal gauged supergravity and show that they are controlled by two constants. Interestingly, the solutions of the equations of motion in the twoderivative theory are not modified by the higherderivative corrections. I will use this to arrive at a general formula for the regularized onshell action for any asymptotically locally AdS4 solution of the theory and show how the higher derivative corrections affect black hole thermodynamic quantities in a universal way. I will employ these results in the context of holography to derive new explicit results for the subleading corrections in the large N expansion of supersymmetric partition functions on various compact manifolds for a large class of threedimensional SCFTs arising from M2 and M5branes. I will also briefly discuss possible extensions and generalizations of these results.
