2D GRAVITY AND MATRIX MODELS I: 2D GRAVITY
Abstract
Some approaches to 2D gravity which have been developed in the last few years are reviewed. They are physical (Liouville) gravity, topological theories and matrix models. Special attention is paid to matrix models and their interrelations with different approaches. Almost all technical details are omitted, but examples are presented.
Based on lectures given at the XXVII Winter LIYaF School, Feb. 1993.
