Abstract

We study the value distributions of the random analytic functions on the unit disk of the form

$$f_\omega(z)= \sum _{j=0}^{\infty}\chi_j(\omega) a_j z^j,$$

where \(a_j\in\mathbb{C}\) and \(\chi_j(\omega)\) are independent and identically distributed random variables defined on a probability space \((\Omega, \mathcal{F}, \mu)\). Some of the theorems complement the work in [6], which deals with random entire functions. We first define a family of random analytic functions in the above form, which includes Gaussian, Rademacher, and Steinhaus analytic functions. Then we prove the relationship between the integrated counting function \(N(r, a, f_\omega)\) and the \(L_2\) norm of \(f\) on the circle \(|z|=r\) as \(r\) is close to \(1\). As a by-product, we obtain Nevanlinna's second main theorem on the unit disk. Finally, we show theorems on the maximum modulus of \(f\) and \(f_\omega\) on the unit disk.

期刊介绍: Traditionally the emphasis of Analysis Mathematica is classical analysis, including real functions (MSC 2010: 26xx), measure and integration (28xx), functions of a complex variable (30xx), special functions (33xx), sequences, series, summability (40xx), approximations and expansions (41xx). The scope also includes potential theory (31xx), several complex variables and analytic spaces (32xx), harmonic analysis on Euclidean spaces (42xx), abstract harmonic analysis (43xx). The journal willingly considers papers in difference and functional equations (39xx), functional analysis (46xx), operator theory (47xx), analysis on topological groups and metric spaces, matrix analysis, discrete versions of topics in analysis, convex and geometric analysis and the interplay between geometry and analysis.
