Description
I will talk about the functional approach to conformal bootstrap. Analytic functionals provide a bootstrap basis, that is built on the analytic understanding of a CFT. This method has a direct connection to the Mellin/Polyakov bootstrap, and fixes the so-called "polynomial ambiguity" that limits the applicability of the latter. I will explain this for the case of boundary CFT-s, where we have two different spectrum of operators to fix. Finally I will demonstrate an example, which will be the epsilon expansion.
