Abstract: (l,m)-uniform混和超級圖的色譜一定是是連續的, 利用一個技巧讓所有l大於二的(l,m)-uniform混和超級圖都存在一組C-edges 和 D-edges, 使得光譜不連續.最後提供一個演算法, 讓所有l和m 都大於二的(l,m)-uniform混和超級圖, 也存在一組 C-edges 和 D-edges, 使得光譜不連續. 這樣我們就已經討論完所有(l,m)-uniform混和超級圖( l , m 都要大於等於 2), 其光譜是否存在著有不連續的可能.
In this thesis, we study all existences of gap in every kind of (l,m)-uniform mixed hypergraph, where n > 1 and m > 1. We have to divide the topic into three parts: (2,m)-uniform mixed hypergraph where m > 1, (l,2)-uniform mixed hypergraph
where l > 2, and (l,m)-uniform mixed hypergraph where l > 2 and m > 2.
