Solvability of a second order nonlinear neutral delay difference equation. (English) Zbl 1252.39001

Abstr. Appl. Anal. 2011, Article ID 328914, 24 p. (2011).
Summary: We study the second-order nonlinear neutral delay difference equation \[ \Delta [a_n \Delta (x_n + b_n x_{n-\tau}) + f(n, x_{f_{1n}}, \dots, x_{f_{kn}})] + g(n, x_{g_{1n}}, \dots, x_{g_{kn}}) = c_n,\;n \geq 0. \] By means of the Krasnosel’skii and Schauder fixed point theorems and some new techniques, we get the existence results of uncountably many bounded nonoscillatory, positive, and negative solutions for the equation, respectively. Ten examples are given to illustrate the results presented in this paper.
