摘要：
We prove a sharp order estimate for entire functions of completely regular growth, whose zeros are distributed near finitely many rays arg z = omega(j) in terms of the angles omega(j) . This result then leads immediately to a proof of a conjecture of Hellerstein and Rossi concerning the distribution of zeros of the solutions of linear differential equations with polynomials coefficients.
