摘要
讨论了非线性脉冲扰动下带强迫项的二阶次线性时滞微分方程'''1(()())()()()()()0niiirtxtptxtqtxθtσht=++∑-+=,t≠tk,0<θ<1,1ix'(tk+)-x'(tk)=Ik(x'(tk)),x(tk+)-x(tk)=Jk(x(tk)),t=tk,k=1,2,…,t≥t0,解的渐近性。利用脉冲微分不等式和分析技巧获得了该方程所有非振动解或振动解趋于零的一系列充分性条件,所得结果推广了现有文献中的结论。
We mainly discuss the asymptotic behavior of solution for forced second order sub-linear delay differential equations (r(t)x'(t))+p(t)x'(t)+∑i=1^n qi(t)x^θ(t-σi)+h(t),t≠tk,0〈θ〈1,x'(tk^+)-x'(tk)=Ik(x'(tk)),x(tk^+)-x(tk)=Jk(x(tk)),t=tk,k=1,2,…,t≥t0, under nonlinear impulsive perturbations. By impulsive differential inequality and some analysis skills, sufficient conditions are obtained for every nonoscillatory or oscillatory solutions of this equation tending to zero. Some known results in the literature are extended and improved.
