Description
I will revise recent developments in the calculation of conformal blocks and its relation to black hole perturbations, especially the calculation of quasinormal modes for generic black hole solutions. A number of conformal operators are related to the black hole in asymptotically flat and anti-de Sitter spacetimes, including primary and Whittaker operators. An alternative view in terms of isomonodromy will be outlined and the symplectic structure ensuing from the equivalence will be described. I will close by explaining how quasinormal modes generically feature properties associated to quantum open systems, such as decay and hysteresis.
