为建立在的 1-set-contractive 地基于拓扑的度[11 ] ,我们在 Menger PN 空间与 accretive mappings 为非线性的方程讨论 1-set-contractive 不安和零个点的存在并且获得一些新结果。
Based on the topological degree for 1-set-contractive fields established in [11], we discuss the 1-set-contractive perturbation and the existence of zero points for nonlinear equations with accretive mappings in Menger PN-spaces and obtain some new results.
