POSITIVE SOLUTION OF EVEN ORDER NONLINEAR NEUTRAL DIFFERENCE EQUATIONS WITH VARIABLE DELAY
【摘要】 本文考虑具有可变时滞的偶数阶非线性中立型差分方程,利用Banach空间的压缩映象原理,得到了这类方程存在最终正解的判别准则.
【Abstract】 Positive solutions for a class of high order nonlinear neutral difference equations with variable delay are studied in this paper. By the principle of contraction mapping in Banach space, existence criteria for eventually positive solutions are obtained.
