Smooth Multi-Trace Statistics of Classical Ensembles: Large $N$ Expansions, Cumulants, and Matrix Integrals

BenoÃ®t Collins, Manasa Nagatsu

We consider expectations of the form $E [t r h_{1} (X_{1}^{N}) ... t r h_{r} (X_{r}^{N})]$ , where $X_{i}^{N}$ are self-adjoint polynomials in various independent classical random matrices and $h_{i}$ are…

Weingarten calculus for centered random permutation matrices

BenoÃ®t Collins, Manasa Nagatsu

We introduce and study the Weingarten calculus for centered random permutation matrices in the symmetric group S_N. After presenting a formulation of the Weingarten calculus on the…
