The Chern-Simons One-form and Gravity on a Fuzzy Space
نویسنده
چکیده
The one-dimensional N ×N -matrix Chern-Simons action is given, for large N and for slowly varying fields, by the (2k + 1)-dimensional Chern-Simons action SCS , where the gauge fields in SCS parametrize the different ways in which the large N limit can be taken. Since some of these gauge fields correspond to the isometries of the space, we argue that gravity on fuzzy spaces can be described by the one-dimensional matrix Chern-Simons action at finite N and by the higher dimensional Chern-Simons action when the fuzzy space is approximated by a continuous manifold.

The Matrix Chern-Simons One-form as a Universal Chern-Simons Theory
We consider different largeN limits of the one-dimensional Chern-Simons action i ∫ dt Tr(∂0+ A0) where A0 is an N ×N antihermitian matrix. The Hilbert space on which A0 acts as a linear transformation is taken as the quantization of a 2k-dimensional phase space M with different gauge field backgrounds. For slowly varying fields, the large N limit of the onedimensional CS action is equal to the ...
متن کاملEffects of Chern-Simons gravity on bodies orbiting the Earth
One of the possible low-energy consequences of string theory is the addition of a Chern-Simons term to the standard Einstein-Hilbert action of general relativity. It can be argued that the quintessence field should couple to this Chern-Simons term, and if so, it drives in the linearized theory a parity-violating interaction between the gravito-electric and gravitomagnetic fields. In this paper,...
متن کاملInduced Spin from the ISO(2, 1) Gauge Theory with the Gravitational Chern-Simons Term
In the context of ISO(2, 1) gauge theory, we consider (2 + 1)-dimensional gravity with the gravitational Chern-Simons term (CST). This formulation allows the ‘exact’ solution for the system coupled to a massive point particle (which is not the case in the conventional Chern-Simons gravity). The solution exhibits locally trivial structure even with the CST, although still shows globally nontrivi...
متن کاملErratum: (2+1)-dimensional Chern-Simons gravity as a Dirac square root
For simple enough spatial topologies, at least four approaches to (2 + 1)-dimensional quantum gravity have been proposed: Wheeler-DeWitt quantization, canonical quantization in Arnowitt-Deser-Misner (ADM) variables on reduced phase space, Chern-Simons quantization, and quantization in terms of Ashtekar-Rovelli-Smolin loop variables. An important problem is to understand the relationships among ...
متن کاملGeneralised Chern-Simons actions for 3d gravity and κ-Poincaré symmetry
We consider Chern-Simons theories for the Poincaré, de Sitter and anti-de Sitter groups in three dimensions which generalise the Chern-Simons formulation of 3d gravity. We determine conditions under which κ-Poincaré symmetry and its de Sitter and anti-de Sitter analogues can be associated to these theories as quantised symmetries. Assuming the usual form of those symmetries, with a timelike vec...
