本文给出k连续映射和k道路连通性的定义.讨论^连续映射等价刻画和性质,证明了k连续满映射保持k连通性和k道路连通性,进而研究k道路连通性的基本性质,证明了k道路连通性是k连通的.k道路连通性是同胚不变性和有限可积;最后讨论k道路连通分支。
In this paper, we give the definitions of k- continuous mapping and k- path connectedness, discuss the characterizations and basic properties of k- continuous mapping, show that it can preserve k- connectedness and k- path connectedness. What's more. we study the properties of k--path eonnectedness, and prove that it is topological invariance and finite multiplicative property. Finally, we discuss k--path connected component.
