摘要:

我们研究了 $d \leq 2$ 维下次临界高斯乘性混沌(GMCs)的“临界矩”。特别地,我们建立了一个完全显式的首阶渐近公式,该公式与 GMCs 的大偏差结果密切相关,并展现出相似的普适性特征。我们推测,我们的结果正确描述了随机矩阵的矩的矩,或更一般地,在整个介观尺度上渐近高斯且对数相关的结构的类似行为。这在圆酉系综(circular unitary ensemble)的整数情形下得到了验证,扩展并加强了 Claeys 等人和 Fahs 的结果至高阶矩。

英文摘要:

We study the 'critical moments' of subcritical Gaussian multiplicative chaos (GMCs) in dimensions $d \leq 2$. In particular, we establish a fully explicit formula for the leading order asymptotics, which is closely related to large deviation results for GMCs and demonstrates a similar universality feature. We conjecture that our result correctly describes the behaviour of analogous moments of moments of random matrices, or more generally structures which are asymptotically Gaussian and log-correlated in the entire mesoscopic scale. This is verified for an integer case in the setting of circular unitary ensemble, extending and strengthening the results of Claeys et al. and Fahs to higher-order moments.
