Stopping Sets of Algebraic Geometry Codes

Jun Zhang, Fang-Wei Fu, Daqing Wan

Stopping sets and stopping set distribution of a linear code play an important role in the performance analysis of iterative decoding for this linear code. Let $C$ be an $[n, k]$ li…

Spectral gap actions and invariant states

Han Li, Chi-Keung Ng

We define spectral gap actions of discrete groups on von Neumann algebras and study their relations with invariant states. We will show that a finitely generated ICC group $Γ$ is i…

On oriented graphs with minimal skew energy

Shicai Gong, Xueliang Li, Guanghui Xu

Let $S (G^{σ})$ be the skew-adjacency matrix of an oriented graph $G^{σ}$ . The skew energy of $G^{σ}$ is defined as the sum of all singular values of its skew-adjacency matrix $S (G^{σ})$ . I…

4-Regular oriented graphs with optimum skew energy

Xiaolin Chen, Xueliang Li, Huishu Lian

Let $G$ be a simple undirected graph, and $G^{σ}$ be an oriented graph of $G$ with the orientation $σ$ and skew-adjacency matrix $S (G^{σ})$ . The skew energy of the oriented graph $G^{σ}$ …

Combinatorial Proof of the Inversion Formula on the Kazhdan-Lusztig R-Polynomials

William Y. C. Chen, Neil J. Y. Fan, Alan J. X. Guo +3

Let $W$ be a Coxeter group, and for $u, v \in W$ , let $R_{u, v} (q)$ be the Kazhdan-Lusztig $R$ -polynomial indexed by $u$ and $v$ . In this paper, we present a combinatorial proof of th…

The generalized 3-connectivity of random graphs

Ran Gu, Xueliang Li, Yongtang Shi

The generalized connectivity of a graph $G$ was introduced by Chartrand et al. Let $S$ be a nonempty set of vertices of $G$ , and $κ (S)$ be defined as the largest number of internal…
