In this paper, we investigate the boundary value problem of a class of fractional (p, q)-difference Schrödinger equations. By applying Banach contraction mapping principle and a fixed point theorem in cones, we obtain the existence and uniqueness of solutions for the boundary value problem. An example illustrating the main results is also presented.

关于非线性分数 (p, q)-差分 Schrödinger 方程

在本文中，我们研究了一类分数( p ,  q )-差分薛定谔方程的边值问题。通过应用Banach收缩映射原理和锥体中的不动点定理，我们得到了边值问题解的存在唯一性。还提供了说明主要结果的示例。
