We compute the deterministic approximation for mixed fluctuation moments of products of deterministic matrices and general Sobolev functions of Wigner matrices. Restricting to …
This thesis is structured into two parts. In the first part, we consider the random variable X:= Tr (f1 (W) A1... fk (W) Ak) where W is an N× N Hermitian Wigner matrix, k∈ N, and we …

We introduce R-diagonal and even operators of second order. We give a formula for the second order free cumulants of the square x2 of a second order even element in terms of the …
