Conformal covariance of the Liouville quantum gravity metric for ??(0,2)

چکیده
For ??(0,2), U?C, and an instance h of the Gaussian free field (GFF) on U, ?-Liouville quantum gravity (LQG) surface associated with (U,h) is formally described by Riemannian metric tensor e?h(dx2+dy2) U. Previous work authors showed that one can define a canonical (distance function) Dh U ?-LQG surface. We show this conformally covariant in sense it respects coordinate change formula for surfaces. That is, if U˜ are domains, ?:U?U˜ conformal transformation, Q=2/?+?/2, h˜=h???1+Qlog|(??1)?|, then Dh(z,w)=Dh˜(?(z),?(w)) all z,w?U. This proves intrinsic to structure (U,h), i.e., does not depend particular choice parameterization.

Liouville quantum gravity and KPZ
Consider a bounded planar domain D, an instance h of the Gaussian free field on D, with Dirichlet energy (2π)−1 ∫ D ∇h(z) · ∇h(z)dz, and a constant 0 ≤ γ < 2. The Liouville quantum gravity measure on D is the weak limit as ε → 0 of the measures ε 2/2eγhε(z)dz, where dz is Lebesgue measure on D and hε(z) denotes the mean value of h on the circle of radius ε centered at z. Given a random (or dete...
متن کاملLiouville Quantum Gravity on the Riemann sphere
In this paper, we rigorously construct 2d Liouville Quantum Field Theory on the Riemann sphere introduced in the 1981 seminal work by Polyakov Quantum Geometry of bosonic strings. We also establish some of its fundamental properties like conformal covariance under PSL2(C)-action, Seiberg bounds, KPZ scaling laws, KPZ formula and the Weyl anomaly (Polyakov-Ray-Singer) formula for Liouville Quant...
متن کاملLiouville Quantum Gravity on the complex tori
In this paper, we construct Liouville Quantum Field Theory (LQFT) on the toroidal topology in the spirit of the 1981 seminal work by Polyakov. Our approach follows the construction carried out by the authors together with A. Kupiainen in the case of the Riemann sphere. The difference is here that the moduli space for complex tori is non trivial. Modular properties of LQFT are thus investigated....
متن کاملWard Identities of Liouville Gravity coupled to Minimal Conformal Matter
The Ward identities of the Liouville gravity coupled to the minimal conformal matter are investigated. We introduce the pseudo-null fields and the generalized equations of motion, which are classified into series of the Liouville charges. These series have something to do with the W and Virasoro constraints. The pseudo-null fields have non-trivial contributions at the boundaries of the moduli s...
متن کاملGeneral Covariance in Quantum Gravity
The question of general covariance in quantum gravity is considered in the first post-Newtonian approximation. Transformation properties of observable quantities under deformations of a reference frame, induced by variations of the gauge conditions fixing general invariance, are determined. It is found that the one-loop contributions violate the principle of general covariance, in the sense tha...
