摘要
在本文中,我们讨论了二阶非齐次微分方程(r(t)x′(t))′+q(t)x(t)=f(t)和非线性微分方程(r(t)x′(t))′+p(t)x(t)+q(t)f(t,x)=0,并建立了其属于L.C(平方可积)的充分条件.
In this paper, we consider the second order nonlinear differential equation and nonnomogeneous differential equation (r(t)x'(t))r + q(t)x(t) = f(t), (r(t)x'(t))r + p(t)x(t) + q(t)f(t,x) = 0,and obtain some suf- ficient conditions under which eqution belongs to L.C.
