چکیده
We consider a model of 2D gravity with the action quadratic in curvature and represent path integrals as over SL(2,R) invariant Gaussian functional measure. reduce these to products Wiener calculate correlation function metric first perturbative order.

Quantum Cosmological Approach to 2d Dilaton Gravity
We study the canonical quantization of the induced 2d-gravity and the pure gravity CGHS-model on a closed spatial section. The Wheeler-DeWitt equations are solved in (spatially homogeneous) choices of the internal time variable and the space of solutions is properly truncated to provide the physical Hilbert space. We establish the quantum equivalence of both models and relate the results with t...
متن کاملDamaging 2D Quantum Gravity
We investigate numerically the behaviour of damage spreading in a Kauffman cellular automaton with quenched rules on a dynamical φ graph, which is equivalent to coupling the model to discretized 2D gravity. The model is interesting from the cellular automaton point of view as it lies midway between a fully quenched automaton with fixed rules and fixed connectivity and a (soluble) fully annealed...
متن کاملQuenching 2D Quantum Gravity
We simulate the Ising model on a set of fixed random φ graphs, which corresponds to a quenched coupling to 2D gravity rather than the annealed coupling that is usually considered. We investigate the critical exponents in such a quenched ensemble and compare them with measurements on dynamical φ graphs, flat lattices and a single fixed φ graph. Submitted to Phys Lett B. 1 Address: Sept. 1993 199...
متن کامل2D String Theory Coupled to Quantum Gravity
We consider self-avoiding Nambu-Goto open strings on a random surface. We have shown that the partition function of such a string theory can be calculated exactly. The string susceptibility for the disk is evaluated to be − 2 . We also consider modifications of the Nambu-Goto action which are exactly soluble on a random surface.
متن کاملLoops in 2d Quantum Gravity*
ADRIAN R. COOPER Stanford Linear Accelerator Center Stanford University, Stanford, California 94309 ABSTRACT We argue that existing discussions of discretised random surfaces with boundaries are incomplete, and give the correct versions for Kazakov’s multicritical models. This leads to the calculation of self-avoiding loops on the surfaces, and uncovers a new type of phase transition. Applying ...
