Near-horizon extremal geometries: coadjoint orbits and quantization

Abstract The NHEG algebra is an extension of Virasoro introduced in [arXiv:1503.07861]; it describes the symplectic symmetries of (n + 4)-dimensional Near Horizon Extremal Geometries with SL(2, ℝ) × U(1) n+ 1 isometry. In this work we construct the NHEG group and classify the (coadjoint) orbits of i...
