AI总结:

本文研究了具有原点谱奇异性的平稳高斯场的持久概率的精确对数渐近行为,并确定了在持久条件下熵排斥分布,该研究适用于一般d维平稳高斯场,结果依赖于参数α和d,并通过α-里斯核的容量和平衡势显式表达。

摘要:

我们计算了具有原点谱奇异性的平稳高斯场的持久概率的精确对数渐近行为,并确定了在持久条件下熵排斥分布,适用于一般d维平稳高斯场,其中谱奇异性的阶数为α∈[0,d)。在温和的正则性条件下,这些结果被证明是通用的,仅依赖于α和d,并通过α-里斯核的容量和平衡势显式表达。这扩展了Bolthausen、Deuschel和Zeitouni关于高斯自由场的结果,应用于更广泛的具有谱奇异性的高斯场。

英文摘要:

We compute the exact log-asymptotics of the persistence probability, and determine the entropic repulsion profile conditioned on persistence, for general $d$-dimensional stationary Gaussian fields with spectral singularity at the origin of order $α\in [0,d)$. Under mild regularity conditions these are shown to be universal, depending only on $α$ and $d$, and to have explicit formulations in terms of the capacity and equilibrium potential of the $α$-Riesz kernel. This generalises a result of Bolthausen, Deuschel and Zeitouni on the Gaussian free field to a wide class of Gaussian fields with spectral singularity.
