Geometrical measurements in three-dimensional quantum gravity
A set of observables is described for the topological quantum field theory which describes quantum gravity in three space-time dimensions with positive signature and positive cosmological constant. The simplest examples measure the distances between points, giving spectra and probabilities which have a geometrical interpretation. The observables are related to the evaluation of relativistic spi...
متن کاملA geometrical action for dilaton gravity
We study the gravitational interaction involving the dilaton and the antisymmetrical Bμν fields that arises in the low-energy limit of string theory. It is shown that such interaction can be derived from a geometrical action principle, with the scalar of curvature of a non-Riemannian, but metric-compatible, connection as the lagrangian, and with a non-parallel volume-element. This action is con...
متن کاملRestrictions on a geometrical language in gravity
It was shown by the author (gr-qc/0207006) that screening the background of super-strong interacting gravitons creates Newtonian attraction if single gravitons are pairing and graviton pairs are destructed by collisions with a body. In such the model, Newton’s constant is connected with Hubble’s constant, for which the estimate is obtained: 94.576 km ·s−1 ·Mpc−1. It is necessary to assume an at...
متن کاملA non-geometrical approach to quantum gravity
Some results of author’s work in a non-geometrical approach to quantum gravity are reviewed here, among them: a quantum mechanism of classical gravity giving a possibility to compute the Newton constant; asymptotic freedom at short distances; interaction of photons with the graviton background leading to the important cosmological consequences; the time delay of photons due to interactions with...
متن کاملDifferential Geometrical Formulation of Gauge Theory of Gravity
Differential geometric formulation of quantum gauge theory of gravity is studied in this paper. The quantum gauge theory of gravity which is proposed in the references hep-th/0109145 and hep-th/0112062 is formulated completely in the framework of traditional quantum field theory. In order to study the relationship between quantum gauge theory of gravity and traditional quantum gravity which is ...
