Description
In the first part of the talk I will review the relation between the anomalies in six dimensions and the Chern-Simons couplings in five. These determine in particular the central charges of string-like BPS objects that cannot be consistently decoupled from gravity, a.k.a. supergravity strings. In the second part of the talk I will review how requiring that the worldsheet theory of the supergravity strings imposes bounds on the admissible theories of quantum gravity.
