常見例句It is clear that for any graph G the space R(G) and R(TG) are homeomorphic. 顯然,對任意一個圖G,空間R(G)和空間R(TG)是同胚的。In this paper, we derive the homeomorphic classes of graphlike manifold with contraction by means of twist operation. 在這篇文章中;通過使用扭轉運算;我們獲得了具有縮影的圖式流形的同胚分類.In this paper , some results on fixed points of homeomorphic maps in metric spaces have been obtained. 本文給出了度量空間中某些同胚非擴張映射不動點存在的充分必要條件。As mathematicians say, “Every simply connected closed 3-manifold is homeomorphic to a 3-sphere. 用數(shù)學語言表達就是“每個單連通3重(3-manifold)封閉體與一個三維球體同胚(homeomorphic)?!?/li>The equivalence of the following three conditions is proved: two solenoids are homeomorphic;they are isomorphic;the two bonding map sequences are equivalent. 證明螺線管同胚、同構和映射序列等價兩兩等價。In this case Lawson topology on upper space UX agree with the Vietoris topology on Com(Max(UX)), which is homeomorphic to Max(C(UX)) with the Scott topology inherited from the C(UX). X的上空間UX上的Lawson拓撲與X緊子集上的Vietoris拓撲相同;并且與Max(C(UX))帶有C(UX)上的相對Scott拓撲同胚. 返回 homeomorphic
