随机双纽系统节点分量期望数的渐近性

Asymptotics for the expected number of nodal components for random lemniscates

Zakhar Kabluchko, Igor Wigman

摘要:

我们确定真正的渐近行为的预期数量的连接组件的随机lemniscates最近提出的Lerario和Lundberg模型。这些被定义为黎曼球面的子集,其中某个随机的、$\text{SO}(3)$ -不变的有理函数的次数$n$的绝对值等于$1$。我们表明,这些双纽线,除以$n$,连接组件的预期数量收敛到一个正的常数定义的两个独立的平面高斯解析函数的商。由于Nazarov和Sodin在这个问题上应用新的非局部技术的一个主要障碍是潜在的非高斯性,与所研究的模型无关。

英文摘要:

We determine the true asymptotic behaviour for the expected number of connected components for a model of random lemniscates proposed recently by Lerario and Lundberg. These are defined as the subsets of the Riemann sphere, where the absolute value of certain random, $\text{SO}(3)$-invariant rational function of degree $n$ equals to $1$. We show that the expected number of the connected components of these lemniscates, divided by $n$, converges to a positive constant defined in terms of the quotient of two independent plane Gaussian analytic functions. A major obstacle in applying the novel non-local techniques due to Nazarov and Sodin on this problem is the underlying non-Gaussianity, intristic to the studied model.
