Abstract

In this paper, we study second-order \(m\)-point difference boundary value problems on infinite intervals \[ \left\{\begin{array}{l} \Delta^{2}x(k-1)+f(k,x(k),\Delta x(k-1))=0,~k\in N,\\ x(0)=\sum\limits_{i=1}^{m-2}\alpha_{i}x(\eta_{i}),~\lim\limits_{k \rightarrow\infty }\Delta x(k)=0, \end{array} \right. \] where \(N=\{1,2,\cdots\},\ f:N\times R^{2}\rightarrow R\) is continuous, \(\alpha_{i}\in R,~\sum\limits_{i=1}^{m-2}\alpha_{i}\neq1,~\eta_{i}\in N,~0<\eta_{1}<\eta_{2}<\cdots<\infty\) and \[\Delta x(k)=x(k+1)-x(k),\] the nonlinear term is dependent in a difference of lower order on infinite intervals. By using Leray-Schauder continuation theorem, the existence of solutions are investigated. Finally, we give one example to demonstrate the use of the main result.
