Abstract
The generalized orthogonal ensemble satisfies isoperimetric inequalities an alogous to the Gaussian isoperimetric inequality, and an analogue of Wigner 's law. Let v be a continuous and even real function such that V(X) = trace v(X)/n defines a uniformly p-convex function on the real symmetric n x n m atrices X for some p greater than or equal to 2. Then v(dX) = e(-V(X))dX/Z satisfies deviation and transportation inequalities analogous to those sati sfied by Gaussian measure((6, 27)), but for the Schatten c(p) norm. The map , that associates to each X is an element of M-n(s) (R) its ordered eigenva lue sequence, induces from v a measure which satisfies similar inequalities , It follows from such concentration inequalities that the empirical distri bution of eigenvalues converges weakly almost surely to some non-random com pactly supported probability distribution as n --> infinity.
