A bound for the $p$ -domination number of a graph in terms of its eigenvalue multiplicities

A. Abiad, S. Akbari, M. H. Fakharan +1

Let $G$ be a connected graph of order $n$ with domination number $γ (G)$ . Wang, Yan, Fang, Geng and Tian [Linear Algebra Appl. 607 (2020), 307-318] showed that for any Laplacian eig…

On the Chromatic Vertex Stability Number of Graphs

Saieed Akbari, Arash Beikmohammadi, Sandi Klavžar +1

The chromatic vertex (resp.\ edge) stability number $vs_{χ} (G)$ (resp.\ $es_{χ} (G)$ ) of a graph $G$ is the minimum number of vertices (resp.\ edges) whose deletion results…

Spectra of strongly Deza graphs

Saieed Akbari, Willem H. Haemers, Mohammad Ali Hosseinzadeh +3

A Deza graph $G$ with parameters $(n, k, b, a)$ is a $k$ -regular graph with $n$ vertices such that any two distinct vertices have $b$ or $a$ common neighbours. The children $G_{A}$ and…

Zero-sum flows for Steiner systems

Saieed Akbari, Hamid Reza Maimani, Leila Parsaei Majd +1

Given a $t$ - $(v, k, λ)$ design, $D = (X, B)$ , a zero-sum $n$ -flow of $D$ is a map $f : B ⟶ {\pm 1, \dots, \pm (n - 1)}$ such that fo…
