Titre  Blackhole collapse in CFT: from conformal blocks to bulk path integrals 
Résumé  Holography (also known as AdS/CFT) is a duality relation that gives us a way of formulating questions about quantum gravity in terms of more ordinary quantum field theories without gravity. A natural and longstanding goal has been to understand the physics of black holes using holographic duality. I will report on some recent progress on this question elucidating the spherical collapse of an infalling shell of null matter in three dimensional quantum gravity. I will end up with describing recent results on the relation between the bulk path integral and the conformal block expansion of the dual CFT.
