D=26 and Exact Solution to the Conformal-gauge Two-dimensional Quantum Gravity
نویسنده
چکیده
The conformal-gauge two-dimensional quantum gravity is formulated in the framework of the BRS quantization and solved completely in the Heisenberg picture: All n-point Wightman functions are explicitly obtained. The eld-equation anomaly is shown to exist as in other gauges, but there is no other subtlety. At the critical dimension D = 26 of the bosonic string, the eld-equation anomaly is shown to be absent. However, this result is not equivalent to the statement that the conformal anomaly is proportional to D ? 26. The existence of the FP-ghost number current anomaly is seen to be an illusion.

An Exact Solution to O(26) Sigma Model Coupled to 2-D Quantum Gravity
By a mapping to the bosonic string theory, we present an exact solution to the O(26) sigma model coupled to 2-D quantum gravity. In particular, we obtain the exact gravitational dressing to the various matter operators classified by the irreducible representations of O(26). We also derive the exact form of the gravitationally modified beta function for the original coupling constant e2. The rel...

It is shown that the BRS-formulated two-dimensional BF theory in the light-cone gauge (coupled with chiral Dirac fields) is solved very easily in the Heisenberg picture. The structure of the exact solution is very similar to that of the BRS-formulated twodimensional quantum gravity in the conformal gauge. In particular, the BRS Noether charge has anomaly. Based on this fact, a criticism is made...

The Wheeler-DeWitt method is applied to the quantization of the 1 + 1 dimensional dilaton gravity coupled with the conformal matter fields. Exact solutions to the WD equations are found, which are classically interpreted as right(left)-moving black holes. E-mail address: [email protected] The two dimensional dilaton gravity recently attracts much attention as a sample model of the four dimensi...
متن کاملTopics in Quantum Geometry of Riemann Surfaces: Two-Dimensional Quantum Gravity
In these lectures, we present geometric approach to the two-dimensional quantum gravity. It became popular since Polyakov’s discovery that first-quantized bosonic string propagating in IR can be described as theory of d free bosons coupled with the two-dimensional quantum gravity [1]. In critical dimension d = 26, the gravity decouples and Polyakov’s approach reproduces results obtained earlier...
متن کاملCENTRAL CHARGE FOR AdS2 QUANTUM GRAVITY
Two-dimensional Maxwell-dilaton quantum gravity on AdS2 with radius l and a constant electric field E is studied. In conformal gauge, this is equivalent to a CFT on a strip. In order to maintain consistent boundary conditions, the usual conformal diffeomorphisms must be accompanied by a certain U(1) gauge transformation. The resulting conformal transformations are generated by a twisted stress ...
