摘要
用分析的方法研究了一类奇数阶非线性中立型时滞差分方程Δd(a(n)x(n)-p(n)x(n-τ))+∑sj=1qj(n)fj(x(n-σj))=0的振动性,得到了该方程振动的若干新的充分条件,推广并改进了现有文献中的结果.
By using the method of analysis ,the oscillation for a class of the higher order nonlinear neutral delay difference equation Δd(a(n)x(n)-p(n)x(n-τ))+∑sj=1qj(n)fj(x(n-σj))=0 is studied in this paper. Some new sufficient conditions for the oscillation of the equations are obtained. The results improve and extend some existing results in the literature.
