The paper treats the linear differential equation,
where is an integer, is a transcendental entire function of order . It is shown that any non-trivial solution of satisfies , where is the exponent of convergence of the zero-sequence of , under the condition,
for and an exceptional set, , of finite linear measure. Herein and denotes the counting function and the characteristic function of respectively. A very nice example is given demonstrating the result. Several technical lemmas are extremely well done preparing the proof of the theorem.
The other half of the paper treats the second-order equation,
where and are non-constant polynomials of degree and respectively. is an entire function of order less than . Several theorems are proved regarding equation , where once again several well done lemmas prepare the proof of the theorem. The paper is very well written.
