THE NON-EXISTENCE OF POSITIVE SOLUTION OF A NONLINEAR DIFFERENCE EQUATION WITH UNBOUNDED DELAY
摘要
研究一类非线性无界时滞差分方程及其对偶方程,给出了方程不存在正解的充分条件,所得结论改进了有关的结果.
New sufficient conditions for the non-existence of positive solution to a nonlinear difference equation with unbounded delay and to its dual equation are obtained, and some of the results in the literature are improved.
