摘要 对定义在无线性结构的非紧乘积拓扑空间上的集值映象簇证明了新的重合点定理.作为特殊情形,得到了集值映象簇的聚合不动点定理. New coincidence theorems for families of set valued mappings defined on noncompact product topological spaces without linear structure are proved. As special cases, some collectively fixed point theorems for a family of set-valued mappings are obtained.
