The two theorems above give a complete solution of the problem of complementary cycles in tournaments . however , for multipartite tournaments which are not tournaments , the problem of complementary cycles is still open 以上两个定理已经完全解决了竞赛图的共轭圈问题，而多部竞赛图的共轭圈问题尚未解决。

This dissertation derives the transformation rule between schmidt decomposable multipartite entangled pure states ( schmidt state ) under locc , which is the same as the rule for the bipartite entangled pure - state transformation under locc 得出了schmidt可分解的多体纠缠纯态(简称为schmidt态)的转换规律，发现这种转换规律与两体纠缠纯态的转换规律相同。

In this paper , we extend the theorem of song to multipartite tournaments and prove that every 2 - connected and 2 - equilibrium multipartite tournament contains a pair of componentwise complementary cycles , unless it is isomorphic to t71 ( see figure in ? ) 本文将竞赛图的结果推广到均匀多部竞赛图上，并证明了2 -强连通2 -均匀多部竞赛图包含一对分量共轭圈，除非它同构于竞赛图t _ 7 ~ 1 (参看图1 ) 。

Quantum entanglement shared by more than two particles or parties is the essential base for developing quantum communication networks . using the multipartite entanglement the novel telecloning , controlled dense coding , sharing secure quantum states and reduction of communication complexity can be realized 为了研究量子网络，必需研究两个以上子系统之间的纠缠，即多粒子或多组份纠缠，利用它可以实现远程克隆( telecloning ) 、可控密集编码、共享秘密量子态以及减小通讯复杂性( reductionofthecommunicationcomplexity )等。
