二阶非齐次线性微分方程的振动性

Oscillation of the Second Order Nonhomogeneous Linear Differential Equations

本文研究二阶非齐次线性微分方程(rx)′+qx=f和(ry′)′+q_1y=f_1的解的振动性。在一定条件下,第二个方程是振动的时候,第一个方程也是振动的。

In this paper, we study the oscillatory of solutions of the second order nonhomogeneous linear differential equations (rx')'+ qx=f and (ry')'+q_(xy)=f_1. In certain conditions, when the second equation is oscillatory the first one is oscillatory, too.
