摘要
研究了一类具时滞的非线性变系数差分方程xn+1=xnexp(rn1 -xn-k1 -cxn-k)解的振动性 ,获得了其正解关于正平衡点 x
In this paper,the oscillation of positive sotutions for a type of nonlinear difference equations with variable coefficientsx n+1 =x nexp(r n1-x n-k 1-cx n-k )is investigated,A good sufficient condition for the oscillation about the positive equilibriun =1 is obtained.
