Let [zn] be a sequence of distinct complex numbers such that [zn|→∞ as n→∞. It is supposed that [zn] are arranged according to non-decreasing moduli, the numbers with the same modulus being arranged according to their amplitudes. We shall refer to the exponent of convergence p of [zn] as its order. We suppose 0 < p < ∞. Let σ(z) be the canonical product with simple zeros at zn.
