How do black holes spin in Chern-Simons modified gravity?

No Kerr-like exact solution has yet been found in Chern-Simons modified gravity. Intrigued by this absence, we study stationary and axisymmetric metrics that could represent the exterior field of spinning black holes. For the standard choice of the background scalar, the modified field equations decouple into the Einstein equations and additional constraints. These constraints eliminate essenti...

W Gravity From Chern–Simons Theory

Starting with three dimensional Chern–Simons theory with gauge group Sl(N, IR), we derive an action Scov invariant under both left and right WN transformations. We give an interpretation of Scov in terms of anomalies, and discuss its relation with Toda theory. e-mail: [email protected] e-mail: [email protected]

Super Chern-Simons Quantum Mechanics

The Super Chern-Simons mechanics, and quantum mechanics of a particle, on the coset super-manifolds SU(2|1)/U(2) and SU(2|1)/[U(1)× U(1)], is considered. Within a convenient quantization procedure the well known Chern-Simons mechanics on SU(2)/U(1) is reviewed, and then it is shown how the fuzzy supergeometries arise. A brief discussion of the supersphere is also included. ⋆ To appear in Procee...
