高阶非线性泛函微分方程的强迫振动性
Forced Oscillation of Higher-order Nonlinear Functional Differential Equations
摘要
Abstract
In this paper,a class of higher order nonlinear differential equation of forced oscillation x(n) (t) +m∑i=1qi(t)|x(τ(t))|λ(i)-1x(τ(t)) =e(t),t ∈ [t0,∞],n ∈ Nis mainly discussed,whereλi (i =1,2,…,m) are positive constants satisfyingλ1 <λ2 < … <λm,qi (t);e(t) ∈ C[t 0,∞),τ (t) ∈ C1 [t 0,∞).We impose no restriction on the forcing term e (t) in the equation above.Two cases have been taken into consideration:(i)qi (t)<0,λi > 1,and τ (t)≤t (≥t);(ii) qi (t) changes its sign,0<λi<1,and τ(t)≤t(≥t).关键词
