A conformal block Farey tail
Abstract We investigate the constraints of crossing symmetry on CFT correlation functions. Four point conformal blocks are naturally viewed as functions on the upper-half plane, on which crossing symmetry acts by PSL(2, ℤ $$ \mathbb{Z} $$ ) modular transformations. This allows us to construct a uniq...
