On the radial distribution of Julia sets of entire solutions of f(n)+A(z)f=0

This paper is devoted to studying the dynamical properties of solutions of f(n)+A(z)f=0, where n(⩾2) is an integer, and A(z) is a transcendental entire function of finite order. We find the lower bound on the radial distribution of Julia sets of E(z) provided that E=f1f2⋯fn and {f1,f2,…,fn} is a solution base of such equations.
