We consider type II superstrings on AdS backgrounds with Ramond-Ramond flux in various dimensions. We realize the backgrounds as supercosets and analyze explicitly two classes of models: non-critical…

A large class of modifications of the standard Lagrangian for two-dimensional dilaton gravity have extremal solutions which are nonsingular analogues of the extremal Reissner-Nordstr\"om spacetime, and it is possible that quantum deformations of these extremal solution are the end point of Hawking evaporation when the models are coupled to matter.
