On the modular Erdős-Burgess constant

Jun Hao, Haoli Wang, Lizhen Zhang

Let $n$ be a positive integer. For any integer $a$ , we say that $a$ is idempotent modulo $n$ if $a^{2} \equiv a (mod n)$ . The $n$ -modular Erdős-Burgess constant is the smallest positiv…

On the Erdős-Burgess constant of the multiplicative semigroup of a factor ring of $F_{q} [x]$

Haoli Wang, Jun Hao, Lizhen Zhang

Let $S$ be a commutative semigroup endowed with a binary associative operation $+$ . An element $e$ of $S$ is said to be idempotent if $e + e = e$ . The {\sl Erdős-Bu…

An upper bound for the crossing number of augmented cubes

Guoqing Wang, Haoli Wang, Yuansheng Yang +2

A {\it good drawing} of a graph $G$ is a drawing where the edges are non-self-intersecting and each two edges have at most one point in common, which is either a common end vertex…

On the 3- $γ_{t}$ -Critical Graphs of Order $Δ (G) + 3$

Haoli Wang, Xirong Xu, Yang Yuansheng +1

Let $γ_{t} (G)$ be the total domination number of graph $G$ , a graph $G$ is $k$ -total domination vertex critical (or\ just\ $k$ - $γ_{t}$ -critical) if $γ_{t} (G) = k$ , and for any vertex $v$ o…
