We construct a Chern-Simons type gauged N = 8 supergravity in three spacetime dimensions with gauge group SO(4) Ã— Tâˆž over the infinite dimensional coset space SO(8,âˆž)/ (SO(8) Ã— SO(âˆž)), where Tâˆž is anâ€¦ (More)

Following the recent construction of maximal (N = 16) gauged super-gravity in three dimensions, we derive gauged D = 3, N = 8 supergravities in three dimensions as deformations of the correspondingâ€¦ (More)

We apply Senâ€™s entropy formalism to the study of the near horizon geometry and the entropy of asymptotically AdS black holes in gauged supergravities. In particular, we consider non-supersymmetricâ€¦ (More)

We construct supersymmetric deformations of general, locally supersymmetric, nonlinear sigma models in three spacetime dimensions, by extending the pure su-pergravity theory with a Chern-Simons termâ€¦ (More)

We assemble the spectrum of single-trace operators in free N = 4 SU (N) SYM theory into irreducible representations of the Higher Spin symmetry algebra hs(2, 2|4). Higher Spin representations orâ€¦ (More)

The canonical quantization of the essentially nonlinear midisuperspace model describing cylindrically symmetric gravitational waves with two polarizations is presented. A Fock space typeâ€¦ (More)

Dimensional reduction of various gravity and supergravity models leads to effectively two-dimensional field theories described by gravity coupled G/H coset space Ïƒ-models. The transition matrices ofâ€¦ (More)

Recently, gauged supergravities in three dimensions with Yang-Mills and ChernSimons type interactions have been constructed. In this article, we demonstrate that any gauging of Yang-Mills type withâ€¦ (More)

Cylindrical gravitational waves of Einstein gravity are described by an integrable system (Ernst system) whose quantization is a long standing problem. We propose to bootstrap the quantum theoryâ€¦ (More)
