Corrections to Classical Matrix Ensemble Moments, Non-Crossing Annular Pairings, and Ribbon Graphs

Anas A. Rahman, Daniel Munoz George, James A. Mingo

We elucidate a bijection between ribbon graphs on the real projective plane and non-crossing annular pairings that relate to the $1/ N$ correction term of the GOE and LOE spectral m…

Infinitesimal freeness for orthogonally invariant random matrices

Guillaume Cébron, James A Mingo

We introduce a new kind of free independence, called real infinitesimal freeness. We show that independent orthogonally invariant with infinitesimal laws are asymptotically real in…

Asymptotic limit of cumulants and higher order free cumulants of complex Wigner matrices

James A. Mingo, Daniel Munoz George

We compute the fluctuation moments $α_{m_{1}, \dots, m_{r}}$ of a Complex Wigner Matrix $X_{N}$ given by the limit $lim_{N \to \infty} N^{r - 2} k_{r} (T r (X_{N}^{m_{1}}), \dots, T r (X_{N}^{m_{r}}))$ .…
