令G為一個圖(graph),若G的邊(edges)可分解成t個同構之子圖,則此t個子圖稱為G的t-split,且稱G是可t分解的(t-splittable)。 在這個論文裡,我們證明了以下的結果。 一、 設Q為一個重邊數為2,且總邊數可被3整除的多重路徑(multipaths),則Q為可三分解的。 二、 設C為一個重邊數為2,且總邊數可被3整除的多重圈(multicycles),則C為可三分解的。
Let G be a graph and t be a positive integer. A t-split of G is a partition of the edges of G into t isomorphic subgraphs. A graph is said to be t-splittable if it has a t-split. In this thesis we prove the following results. Theorem. Let Q be a multipath with multiplicity 2 such that jE(Q)j=0 (mod 3). Then Q is 3-splittable. Theorem. Let C be a multicycle with multiplicity 2 such that jE(C)j=0 (mod 3). Then C is 3-splittable.
