一类三阶中立型时滞差分方程正解的存在性

ON THE EXISTENCE OF POSITIVE SOLUTION FOR A KIND OF THE THIRD ORDER NEUTRAL DELAY DIFFERENCE EQUATIONS

本文将文[2]中关于具有变系数的二阶中立型时滞差分方程正解的存在性加以推广,研究了具有变系数的三阶中立型时滞差分方程正解的存在性.

In this paper, we generalize the paper [2] on the existence of positive solution for the second order neutral delay difference equations with variable coefficients, and study the case of the third order.
