Abstract

We study the distribution of zeroes of power series with infinite radius of convergence. The coefficients of the series have the form ξ(n)a(n), where a is a smooth sequence of positive numbers, and ξ is a sequence of complex-valued multipliers having binary correlations and no gaps in the spectrum. We show that under certain assumptions on the smoothness of the sequence a and on the binary correlations of the multipliers ξ, the zeroes of the power series are equidistributed with respect to a radial measure defined by the sequence a. We apply our approach to several examples of the sequence ξ: (i) IID sequences, (ii) sequences e(αn2) with Diophantine α, (iii) random multiplicative sequences, (iv) the Golay–Rudin–Shapiro sequence, (v) the indicator function of the square-free integers, (vi) the Thue–Morse sequence.
