二部图上完美匹配的正交匹配分解

给定简单二部图G=（V，E），最大度是k（k≥3），G有一个完美匹配M={e1，e2，…，ek}。称边集E的划分{E1，E2，…，El}是G的一个关于肼的正交匹配分解，如果对每一个El是G的匹配并且包含且仅包含肼中的一条边。在本文中我们将证明对于简单二部图G，存在关于完美匹配肼的正交匹配分解，并给出了求这个分解的多项式时间算法。

具有模糊变量的线性规划问题

讨论含模糊变量的线性规划问题，研究了其求解方法。利用新定义的模糊数序关系，将它转换成一个多目标线性规划问题，然后进一步转换成两层多目标线性规划问题，进而利用分层规划法求解。     

A Kind of Generalization of the Curve Type Node Configuration in R^S（S 〉 2）

A kind of generalization of the Curve Type Node Configuration is given in this paper,and it is called the generalized node configuration CTNCB in RS(S＞2).The related multivariate polynomial interpolation problem is discussed.It is proved that the CTNCB is an appropriate node configuration for the polynomial space PSn (S＞2).And the expressions of the multivariate Vandermonde determinants that are related to the Odd Curve Type Node Configuration in R2 are also obtained.     

广度kdv方程的精确解:改进的齐次平衡法

In this paper,we present a solution methodology to obtain exact solutions of some nonlinear evolution equation by modifying the homogeneous balance method.Based on the modified homogeneous balance method,several kinds of exact(new)solutions of the generalized KdV equation are obtained.     

Multipartite Entanglement in Heisenberg Model

The effects of anisotropy and magnetic field on multipartite entanglement of ground state in Heisenberg XY model are investigated. The multipartite entanglement increases as a function of the inverse strength of the external field when the degree of anisotropy is finite. There are two peaks when the degree of anisotropy is γ=±1. When the degree of anisotropy increases further, the multipartite entanglement will decrease and tend to a constant. The threshold of the inverse strength of the external field for generating multipartite entanglement generally decreases with the increasing of qubits.
