A recursion formula for the moments of the gaussian orthogonal ensemble
Annales de l'I.H.P. Probabilités et statistiques, Tome 45 (2009) no. 3, pp. 754-769.

Ce travail présente un analogue de la relation de récurrence de Harer et Zagier pour les moments de l'Ensemble Orthogonal gaussien sous la forme d'une récurrence à cinq termes. La démonstration s'appuie sur des intégrations par parties gaussiennes et des équations différentielles sur les transformées de Laplace. Une relation similaire est établie pour l'Ensemble Symplectique gaussien. Comme dans le cas complexe, cette relation s'interprète comme une formule de récurrence pour le nombre de cartes enracinées à nombre de faces et de côtés donné plongées dans des surfaces localement orientées. Cette relation de récurrence sur les moments fournit également une borne sur la loi de la plus grande valeur propre de l'Ensemble Orthogonal gaussien et, par comparaison de moments, de familles de matrices de Wigner.

We present an analogue of the Harer-Zagier recursion formula for the moments of the gaussian Orthogonal Ensemble in the form of a five term recurrence equation. The proof is based on simple gaussian integration by parts and differential equations on Laplace transforms. A similar recursion formula holds for the gaussian Symplectic Ensemble. As in the complex case, the result is interpreted as a recursion formula for the number of 1-vertex maps in locally orientable surfaces with a given number of edges and faces. This moment recurrence formula is also applied to a sharp bound on the tail of the largest eigenvalue of the gaussian Orthogonal Ensemble and, by moment comparison, of families of Wigner matrices.
