In this paper we discuss the classical problem of finding conditions that the entire coefficients A(z) and B(z) should satisfy to ensure all nontrivial solutions of f+A(z)f+B(z)f=0 are of infinite order. Two different approaches are used. In the first approach the entire coefficient B(z) has dynamical property with a multiply connected Fatou component, and A(z) is extremal for Yang’s inequality or a nontrivial solution of w+P(z)w=0, where P(z) is a polynomial. In the second approach B(z) satisfies T(r,B)logM(r,B) outside a set of finite logarithmic measure, and A(z) has the same properties as in the first approach.

具有整体系数的二阶复微分方程解的无限增长

在本文中,我们讨论了寻找条件的经典问题,即整个系数 一种žž 应该满足以确保所有非平凡的解 F+一种žF+žF=0是无限的顺序。使用了两种不同的方法。在第一种方法中,整个系数ž 具有动力学特性,并具有多个相连的Fatou分量,并且 一种ž 对于杨的不等式或对 w+Pžw=0,在哪里 Pž是一个多项式。在第二种方法ž 满足 Ť[R日志中号[R 在一组有限的对数度量之外,并且 一种ž 具有与第一种方法相同的属性。
