摘　　要：本文在没有任何线性和凸结构的一般拓扑空间中证明了一个新的连续选择定理.作为应用,在一般拓扑空间框架下得到了一些不动点定理,叠合点定理,极大极小不等式以及一个非空交定理.最后,本文给出了非空交定理的一些等价形式.A new continuous selection theorem is proved in general topological spaces without any linear and convex structure, and next, as applications, some fixed-point theorems, coincidence theorems, minimax inequalities, and a nonempty intersection theorem are obtained in the setting of general topological spaces. Finally, this paper gives some equivalent formulations of the nonempty intersection theorem.
