二阶复域微分方程解的径向振荡
Radial oscillation of solutions of second order complex differential equations
摘要
Abstract
This paper explores the radial oscillation of solutions of linear differential equations f″+B (z)f′+A(z)f=0,where A(z) and B(z) are entire functions. With some added conditions on coefficients,we obtained some estimates of growth of solutions in the angular domains.关键词
