Résumé: 

Liouville conformal field theory (LCFT) is a family of CFTs
which arise in a wide variety of contexts in the physics literature. There
are two main (seemingly unrelated) approaches to LCFT in the physics
literature: one in the Feynman path integral formulation and one in the
conformal bootstrap approach. Recently, we constructed rigorously LCFT in
the Feynman path integral formulation. In this talk, I will present recent
results on the local conformal structure of LCFT in the Feynman path
integral formulation (Ward and BPZ identities, operator product expansion,
etc...). These results are a first step in showing that both approaches in
the physics literature (Feynmam path integral and conformal bootstrap) are
in fact identical.
