摘要
利用值分布理论研究了2阶周期微分方程中的扰动问题,得到了系数为无穷e-型级周期整函数方程的一些扰动结果,完善了蒋翼迈和高仕安文中的扰动结果.
The perturbation problem of periodic second order differential equation is investigated by using value distribution theory and some perturbation results are obtained for equation with periodic entire coefficients of infinite e-type order. The results of the results due to Chiang Yik-Man and Gao Shi-An are generalized.
