摘要
研究了二阶微分方程解的e-型级Borel方向,运用角域内的Nevanlinna理论,建立了亚纯函数的e-型级Borel方向的一个充要条件,应用这一充要条件,研究了一类二阶微分方程解的e-型级Borel方向与e-型级零点收敛指数之间的关系。
In this paper, we introduce the concept of Borel direction of e-type order and give asucient and necessary condition for it. As an application,we establish the connection between the e-type ex- ponent of convergence of the zeroes and Borel direction of e-type order for the solutions of second or- der differential equation with transcendental entire function coeffcients.
