註釋Abstract: "Given a subspace X [subset] R[superscript d] and a finite set S [subset] R[superscript d], we introduce the Delaunay simplicial complex, D[subscript x], restricted by X. Its simplices are spanned by subsets T [subset] S for which the common intersection of Voronoi cells meets X in a non-empty set. By the nerve theorem, [union] D[subscript x] and X are homotopy equivalent if all such sets are contractible. This paper shows that [union] D[subscript X] and X are homeomorphic if the sets can be further subdivided in a certain way so they form aregular CW complex."
