Аннотация:We find the greatest lower bound for the type of an entire function of order ρ∈(0,1) whose sequence of zeros lies on one ray and has prescribed lower and upper ρ-densities. We make a thorough study of the dependence of this extremal quantity on ρ and on properties of the distribution of zeros. The results are applied to an extremal problem on the radii of completeness of systems of exponentials.
