We review recent developments in Jackiw–Teitelboim gravity. This is a simple solvable
model of quantum gravity in two dimensions (that arises eg from the s-wave sector of higher …

In these lecture notes I consider one remarkable system of differential equations that
appeared in the papers of physicists on two-dimensional topological field theory (TFT) in the …

We present exact results for partition functions of Jackiw-Teitelboim (JT) gravity on two-
dimensional surfaces of arbitrary genus with an arbitrary number of boundaries. The …

A bstract We propose that a class of new topologies, for which there is no classical solution,
should be included in the path integral of three-dimensional pure gravity, and that their …

Recently, it has been found that Jackiw-Teitelboim (JT) gravity, which is a two-dimensional
theory with bulk action− 1/2∫ d 2 xg ϕ (R+ 2), is dual to a matrix model, that is, a random …

Quantum gravity poses the problem of merging quantum mechanics and general relativity,
the two great conceptual revolutions in the physics of the twentieth century. The loop and …

String theory is one of the most exciting and challenging areas of modern theoretical
physics. This book guides the reader from the basics of string theory to recent developments …

These are notes based on two lectures given at the Conference on Geometry and Topology
(Harvard University, April 1990). The first was mainly devoted to explaining a conjecture …

We review recent progress in 2D gravity coupled to d< 1 conformal matter, based on a
representation of discrete gravity in terms of random matrices. We discuss the saddle point …
