摘要 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))+q(n)f(x(n-σ))=0的振动性,得到了该方程振动的若干充分条件,推广并改进了现有文献中的结果. The oscillation is studied for a class of nonlinear odd-order neutral delay difference equations △d(a(n)x(n)-p(n)x(n-τ))+q(n)f(x(n-σ))=0. Some sufficient conditions for the oscillation of the equations are obtained. Some existing results in the literature are improved and extended.
