Uniform asymptotics of the coefficients of unitary moment polynomials

Ghaith A. Hiary, Michael O. Rubinstein

摘要:

Keating和Snaith证明了单位圆上随机酉矩阵的特征多项式的$2k^{th}$绝对矩由$k^2$次多项式给出。在这篇文章中,该多项式的系数的一致渐近推导,并找到一个最大的系数。某些渐近性以显式形式给出。数值数据来支持这些计算。随机矩阵理论和黎曼zeta函数之间的一些明显的联系进行了讨论。

英文摘要:

Keating and Snaith showed that the $2k^{th}$ absolute moment of the characteristic polynomial of a random unitary matrix evaluated on the unit circle is given by a polynomial of degree $k^2$. In this article, uniform asymptotics for the coefficients of that polynomial are derived, and a maximal coefficient is located. Some of the asymptotics are given in explicit form. Numerical data to support these calculations are presented. Some apparent connections between random matrix theory and the Riemann zeta function are discussed.
