Generalized Connectivity of Star Graphs

Xiang-Jun Li, Jun-Ming Xu

This paper shows that, for any integers $n$ and $k$ with $0 ⩽ k ⩽ n - 2$ , at least $(k + 1)! (n - k - 1)$ vertices or edges have to be removed from an $n$ -dimensional star gr…

Edge-Fault Tolerance of Hypercube-like Networks

Xiang-Jun Li, Jun-Ming Xu

This paper considers a kind of generalized measure $λ_{s}^{(h)}$ of fault tolerance in a hypercube-like graph $G_{n}$ which contain several well-known interconnection networks such as…

Generalized Measures of Fault Tolerance in Exchanged Hypercubes

Xiang-Jun Li, Jun-Ming Xu

The exchanged hypercube $E H (s, t)$ , proposed by Loh {\it et al.} [The exchanged hypercube, IEEE Transactions on Parallel and Distributed Systems 16 (9) (2005) 866-874], is obtained…

Relative entropy of entanglement of a kind of two qubit entangled states

Xiao-yu Chen, Li-min Meng, Li-zhen Jiang +1

We in this paper strictly prove that some block diagonalizable two qubit entangled state with six none zero elements reaches its quantum relative entropy entanglement by the a sepa…
