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]
متن کاملChern–Simons Gravity and Holographic Anomalies
We present a holographic treatment of Chern-Simons (CS) gravity theories in odd dimensions. We construct the associated holographic stress tensor and calculate the Weyl anomalies of the dual CFT.

متن کاملA Covariant Formalism for Chern–simons Gravity
Chern–Simons type Lagrangians in d = 3 dimensions are analyzed from the point of view of their covariance and globality. We use the transgression formula to find out a new fully covariant and global Lagrangian for Chern–Simons gravity: the price for establishing globality is hidden in a bimetric (or biconnection) structure. Such a formulation allows to calculate from a global and simpler viewpo...
متن کاملChern-simons Gravity from 3+1-dimensional Gravity
In the context of a Poincaré gauge theoretical formulation, pure gravity in 3 + 1dimensions is dimensionally reduced to gravity in 2 + 1-dimensions with or without cosmological constant Λ. The dimensional reductions are consistent with the gauge symmetries, mapping ISO(3, 1) gauge transformations into ISO(2, 1) ones. One of the reductions leads to Chern-Simons-Witten gravity. The solutions of 2...
متن کاملCanonical quantization of Chern-Simons on the light-front
By performing the canonical quantization of the Abelian Chern-Simons model on the light-front (as suggested by Dirac), we clarify some controversies appearing in recent papers that discuss the relation between the existence of excitations carrying fractional spin and statistics (anyons) and this model. Properties of the Chern-Simons model on the light-front are investigated in detail, following...
