In this language, the space of solutions of AdS3 gravity is understood as a bunch of different orbits of the Virasoro group, characterized by their isotropy group. Because of the existence of a natural symplectic form in each orbit, being this form related to the usual Dirac bracket of the asymptotic charges, the coadjoint orbits approach is a natural starting point for the discussion of several issues arising in the quantization of different sectors of AdS3 gravity, including the statistical interpretation of black hole entropy.
