摘要 应用著名的Dugundji延拓定理和Urysohn引理,将Hilbert空间E中有界闭凸集D上的k-集压缩映射和聚映射延拓到全空间,并给出了其在拓扑度计算方面的应用. In this paper, we extended the k-set contraction mappings and condensing mappings on a bounded convex closed set D in a Hilbert space E to the entire space, and obtained some applications to the calculation of topological degree.
