摘要:

我们研究了具有平稳复高斯系数且其谱测度绝对连续的随机幂级数的零点。我们分析了收敛圆边界附近零点径向密度的精确渐近行为。与hyperbolic Gaussian analytic function(独立同分布系数情形)相比,系数的依赖性通常会降低零点密度,其中谱密度及其零点在此降低中起关键作用。我们还展示了谱测度支撑与收敛圆边界处解析延拓之间的关系。

英文摘要:

We study the zeros of random power series with stationary complex Gaussian coefficients, whose spectral measure is absolutely continuous. We analyze the precise asymptotic behavior of the radial density of zeros near the boundary of the circle of convergence. The dependence of the coefficients generally reduces the density of zeros compared with that of the hyperbolic Gaussian analytic function (the i.i.d. coefficients case), where the spectral density and its zeros plays a crucial role in this reduction. We also show the relationship between the support of the spectral measure and the analytic continuation at the boundary of the circle of convergence.
