中文摘要 |
令Ck代表含有k個點的迴圈。假設G為一個圖且G中不包含子圖Ck,若連接圖G中任意不相鄰的兩點後,所形成的圖就會包含子圖Ck,那我們就稱圖G為Ck飽和圖。 在本論文中,我們對於n點Ck飽和圖提出4種建構法,分別利用完全圖Kk-1之建構法、完全圖Kk/2+1或完全圖K(k+1)/2之建構法、迴圈Ck+1與完全圖Kk-4之建構法及擬似輪圖W(n, k) 之建構法得到n點Ck飽和圖,進而比較所獲得之四種n點Ck飽和圖的邊數。 |
英文摘要 |
Let Ck be a cycle with k edges. Let G be a graph. If there is no k-cycle contained in G and connecting any non-adjacent vertices of G will obtain a k-cycle, then we call G is a Ck saturated graph. In this thesis, we give four constructions to construct a Ck saturated graph with n vertices. Respectively, we use the complete graph Kk-1, complete graphs Kk/2+1and K(k+1)/2, a (k+1)-cycle Ck+1 and a complete graph Kk-4, and a Wheel graph W(n, k) to construct a Ck saturated graph with n vertices. After that we enumerate the edges in each Ck saturated graph with n vertices and compare the numbers of edges of these four Ck saturated graphs with n vertices. |
