Abstract: We calculate the autocorrelation functions (or shifted moments) of the characteristic polynomials of matrices drawn uniformly with respect to Haar measure from the groups U(N), O(2N) and USp(2N). In each case the result can be expressed in three equivalent forms: as a determinant sum (and hence in terms of symmetric polynomials), as a combinatorial sum, and as a multiple contour integral. These formulae are analogous to those previously obtained for the Gaussian ensembles of Random… 
A recursion formula for moments of derivatives of random matrix polynomials
We give asymptotic formulae for random matrix averages of derivatives of characteristic polynomials over the groups USp(2N), SO(2N) and O^-(2N). These averages are used to predict the asymptotic
Characteristic polynomials of random truncations: moments, duality and asymptotics
We study moments of characteristic polynomials of truncated Haar distributed matrices from the three classical compact groups O(N), U(N) and Sp(2N). For finite matrix size we calculate the moments in
Symmetry Transitions in Random Matrix Theory & L-functions
We compute the moments of the characteristic polynomials of random orthogonal and symplectic matrices, defined by averages with respect to Haar measure on SO(2N) and USp(2N), to leading order as N →
Derivatives of random matrix characteristic polynomials with applications to elliptic curves
The value distribution of derivatives of characteristic polynomials of matrices from SO(N) is calculated at the point 1, the symmetry point on the unit circle of the eigenvalues of these matrices. We
Symmetric function theory and unitary invariant ensembles
Representation theory and the theory of symmetric functions have played a central role in Random Matrix Theory in the computation of quantities such as joint moments of traces and joint moments of
Universal Results for Correlations of Characteristic Polynomials: Riemann-Hilbert Approach
We prove that general correlation functions of both ratios and products of characteristic polynomials of Hermitian random matrices are governed by integrable kernels of three different types: a)

The paper addresses the calculation of correlation functions of permanental polynomials of matrices with random entries. By exploiting a convenient contour integral representation of the matrix
Random Matrices, Magic Squares and Matching Polynomials
The variance of the coecients of the polynomials of random unitary matrices is computed and the answer turns out to be intimately related to counting integer stochastic matrices (magic squares).
L-functions and the characteristic polynomials of random matrices
My purpose in these lecture notes is to review and explain the basic ideas underlying the connection between random matrix theory and the moments of L-functions. Both of these subjects are introduced
Integral Moments of L‐Functions
We give a new heuristic for all of the main terms in the integral moments of various families of primitive L‐functions. The results agree with previous conjectures for the leading order terms. Our

Abstract: We present a range of fluctuation and large deviations results for the logarithm of the characteristic polynomial Z of a random N×N unitary matrix, as N→∞. First we show that , evaluated at

Random Matrix Theory and L-Functions at s= 1/2
Abstract: Recent results of Katz and Sarnak [8, 9] suggest that the low-lying zeros of families of L-functions display the statistics of the eigenvalues of one of the compact groups of matrices U(N),
Mean values of L-functions and symmetry
Recently Katz and Sarnak introduced the idea of a symmetry group attached to a family of L-functions, and they gave strong evidence that the symmetry group governs many properties of the distribution
