摘要
在非紧超凸度量空间中的非紧允许集上,建立了一个新的Browder不动点定理.作为应用,在非紧超凸度量空间中,研究了KyFan截口问题和相交问题,并新建了两个KyFan重合定理.
In this paper, a new Browder fixed point theorem is obtained in the noncompact admissible subsets of noncompact hyperconvex metric spaces. As application, in noncompact hyperconvex metric spaces, Ky Fan section question and intersection question are studied, and two new coincidence theorems are established.
