Abstract

Let and be entire functions of order less than 1 with and transcendental. We prove that every solution of the equation , , being has zeros with infinite exponent of convergence.

Summary

Introduction

It is assumed that the reader of this paper is familiar with the basic concepts of Nevanlinna theory 1, 2 such as T r, f , m r, f , N r, f , and S r, f. Let us recall some of the previous results on the linear differential equation y e−zy B z y 0, 1.4 where B z is an entire function of finite order, When B z is polynomial, many authors 3–6 have studied the properties of the solutions of 1.4 . If B z is a transcendental entire function with ρ B / 1, Gundersen 7 proved that every nontrivial solution of 1.4 has infinite order of growth.
