François David: Random matrices and two dimensional quantum gravity
This course is a short introduction to random matrices and applications to two-dimensional quantum gravity. I shall review discrete formulations of two dimensional quantum gravity, planar maps, and the relations with the large N limit of random matrices (planar limit), and various methods to solve random matrix models: Coulomb gas methods, recursion (loop) equations, orthogonal polynomials, etc. The topological expansion, the double scaling limit and KPZ relations will be reviewed. Finally, the links between matrix models, topological 2D gravity and strings (the study of moduli space of surfaces) will be briefly discussed.
Main references that I shall use (the not too advanced material) is:
