Oscillation of Impulsive Neutral Delay Differential Equations with Positive and Negative Coefficients

YU Ai-wen,LI Jian-li(College of Mathematics and Computer Science,Hunan Normal University,Changsha 410081,China)  
Effective sufficient conditions for the oscillation of all solutions of impulsive neutral delay differential equations of the form [x(t)-R(t)x(t-r)]′+P(t)x(t-r)-Q(t)x(t-δ)=0,t≥t0,(*) x(τ+k)=bkx(τk),k=1,2,…(**)are established.It is seen that the oscillatory behavior of all solutions of Eq(*) can be inherited by system(*) and(**) under certain impulsive perturbations(**).
