具强迫项的二阶非线性泛函微分方程解的振动性与渐近性

Oscillation and Asymptotic Property of Solutions for Second Order Nonlinear Functional Differential Equations with Forcing Term

建立一类具有强迫项的二阶非线性泛函微分方程 [p(t,x(t) ) x′(t) ]′ +f(t,x(t) ,x(g(t) ) ,x′(t) ,x′(h(t) ) ) =e(t)的振动准则 ,并讨论解的渐近性 .

Oscillation criterion for second order nonlinear functional differential equations with forcing term \′+f(t,x(t),x(g(t)),x′(t),x′(h(t)))=e(t) is established,and the asymptotic property of its solutions is disscused.
