DESCRIPTION:The conformal bootstrap aims to systematically constraint CFTs
based on crossing symmetry and unitarity.\n\nIn this talk I will introduc
e a new approach to extract information from the crossing symmetry sum rul
es\, based on the construction of linear functionals with certain positivi
ty properties. I show these functionals allow us to derive optimal bounds
on CFT data. Furthemore I will argue that special extremal solutions to cr
ossing form a basis for the crossing equation\, with the functionals livin
g in the dual space. As an application we reconstruct physics of QFTs in A
dS2 from the properties of 1d CFTs.\n\nhttps://indico.math.cnrs.fr/event/4
