Spinor formulation of topologically massive gravity
In the framework of real 2-component spinors in three dimensional spacetime we present a description of topologically massive gravity (TMG) in terms of differential forms with triad scalar coefficients. This is essentially a real version of the Newman-Penrose formalism in general relativity. A triad formulation of TMG was considered earlier by Hall, Morgan and Perjes, however, due to an unfortu...
متن کاملSpinor Couplings to Dilaton Gravity induced by the Dimensional Reduction of Topologically Massive Gravity
A Dirac spinor is coupled to topologically massive gravity and the D = 3 dimensional action is reduced toD = 2 dimensions with a metric that includes both the electromagnetic potential 1-form A and a dilaton scalar φ. The reduced, electrically charged spinor is made a mass eigenstate with a (local) chiral rotation. The non-trivial interactions thus induced are discussed. [email protected] ...
متن کاملRenormalizability of Topologically Massive Gravity
We consider renormalizability of topologically massive gravity in three space-time dimensions. With a usual parametrization of the metric tensor, we establish the statement that topologically massive gravity is in fact renormalizable. In this proof, we make use of not only a recently found, new infrared regularization method of scalar mode but also a covariant ultraviolet regulator with a speci...

We define conserved gravitational charges in -cosmologically extendedtopologically massive gravity , exhibit them in surface integral form about their de-Sitter or flat vacua and verify their correctness in terms of two basic types of solution. e-mail: deser,[email protected] Address after July 15, Physics Department, Middle East Technical University, 06531 Ankara, Turkey. Recently [1], we def...
متن کاملThe black holes of topologically massive gravity
We show that an analytical continuation of the Vuorio solution to three-dimensional topologically massive gravity leads to a two-parameter family of black hole solutions, which are geodesically complete and causally regular within a certain parameter range. No observers can remain static in these spacetimes. We discuss their global structure, and evaluate their mass, angular momentum, and entro...
