Abstract

Let ζ=(ζn) be a complex sequence of genus zero, τ be its exponent of convergence, N(r) be its integrated counting function, π(z)=(1zζn) be the Weierstrass canonical product, and M(r) be the maximum modulus of this product. Then, as is known, the Wahlund-Valiron inequality
lim sup
holds, and this inequality is sharp. It is proved that for the majority (in the probability sense) of sequences \zeta the constant w(\tau) can be replaced by the constant w\left(\frac{\tau}2\right) in the Wahlund-Valiron inequality.
