Self-dual variables, positive-semidefinite action, and discrete transformations in four-dimensional quantum gravity.
A positive semi-definite Euclidean action for arbitrary four-topologies can be constructed by adding appropriate Yang-Mills and topological terms to the Samuel-Jacobson-Smolin action of gravity with (anti)self-dual variables. Moreover, on-shell, the (anti)self-dual sector of the new theory corresponds precisely to all Einstein manifolds in four dimensions. The Lorentzian signature action, and i...
متن کاملWilson loops in four-dimensional quantum gravity.
A Wilson loop is defined, in 4-D pure Einstein gravity, as the trace of the holonomy of the Christoffel connection or of the spin connection, and its invariance under the symmetry transformations of the action is showed (diffeomorphisms and local Lorentz transformations). We then compute the loop perturbatively, both on a flat background and in the presence of an external source; we also allow ...
متن کامل12j-symbols and four-dimensional quantum gravity
We propose a model which represents a four-dimensional version of Ponzano and Regge’s three-dimensional euclidean quantum gravity. In particular we show that the exponential of the euclidean Einstein-Regge action for a 4d-discretized block is given, in the semiclassical limit, by a gaussian integral of a suitable 12j-symbol. Possible developments of this result are discussed.
متن کاملScaling in Four Dimensional Quantum Gravity
We discuss scaling relations in four dimensional simplicial quantum gravity. Using numerical results obtained with a new algorithm called \baby universe surgery" we study the critical region of the theory. The position of the phase transition is given with high accuracy and some critical exponents are measured. Their values prove that the transition is continuous. We discuss the properties of t...
متن کاملDiscrete States in Two-Dimensional Quantum Gravity∗
We review the recent developments in the two-dimensional (super)gravity coupled to c(ĉ) ≤ 1 (super)conformal matter in the conformal gauge. Starting from a pedagogical account of the conformal anomaly in such a system, we show how the system is transformed into the representation in terms of the (free) Liouville field. Some perturbative justification is given to this procedure. The physical sta...
