Erdős-Ko-Rado theorem for vector spaces over residue class rings

Jun Guo

Let $h = \prod_{i = 1}^{t} p_{i}^{s_{i}}$ be its decomposition into a product of powers of distinct primes, and $Z_{h}$ be the residue class ring modulo $h$ . Let $\mathbb{Z}_{h}^{n…

Orthogonal graphs over Galois rings of odd characteristic

Fenggao Li, Jun Guo, Kaishun Wang

Assume that $ν$ is a positive integer and $δ = 0, 1$ or $2$ . In this paper we introduce the orthogonal graph $Γ^{2 ν + δ}$ over a Galois ring of odd characteristic and prove that it is…

t-singular linear spaces

Jun Guo, Kaishun Wang, Fenggao Li

As a generalization of singular linear spaces, we introduce the concept of t-singular linear spaces, make some anzahl formulas of subspaces, and determine the suborbits of t-singul…
