摘要：
考虑离散周期系统多重正解的存在性, 利用非线性Leray-Schauder抉择定理和Krasnoselskii锥不动点定理, 在一定条件下证明了当非线性项奇异时离散周期系统正解的存在性.
关键词: 离散周期系统, 正解, Krasnoselskii锥不动点定理, 存在性
Abstract:
The author devoted to establish the multiplicity of nonnegative solutions to singular discrete perriodic systems. The existence of the solution was obtained using a nonlinear alternative of LeraySchauder and the Krasnoselskii fixed point theorem in cones. It was proved that such a problem has a nonnegative solutions under some reasonable conditions and nonlinear singular.
Key words: discrete periodic systems, positive solution, Krasnoselskii fixed point theorem in cones, existence
