Abstract

Suppose that the linear differential equation

$$w^{(k)}(z)+{\mathop \sum^{k-2}\limits_{j=0}}A_{j}(z)w^{(j)}(z)=0$$

is such that the Aj are entire of finite order, and that A0 is the dominant coefficient in terms of growth. The existence of a fundamental set of solutions each having few zeros is shown to imply that the order of A0 is a positive integer.
