2D QUANTUM GRAVITY,MATRIX MODELS AND GRAPH COMBINATORICS
The purpose of these lectures is to present basic matrix models as practical combinatorial tools, that turn out to be “exactly solvable”. In short, a matrix model is simply a statistical ensemble of matrices with some specific measure,here given as an invariant weight, to be integrated over the relevant matrix …
