The second-order nonlocal difference equation is considered subject to the right-focal boundary conditions The problem is a discrete version of a one-dimensional Kirchhoff-type equation. Existence of at least one positive solution is considered by means of a topological fixed-point theory. Weaker-than-usual conditions are proposed for the coefficient function A.

具有符号变化系数的离散基尔霍夫方程
二阶非局部差分方程 被认为受右焦边界条件的约束 该问题是一维基尔霍夫型方程的离散版本。通过拓扑不动点理论考虑至少一个正解的存在。为系数函数A提出了比通常更弱的条件。
