Spectrum of the Unit-Graph on $Mat_{3} (F_{q})$

Yeşim Demiroğlu Karabulut, Heriberto Espinosa

In this paper, we investigate the spectrum of the unit-graph of the ring of $3 \times 3$ matrices over a finite field $F_{q}$ , which is equivalently the Cayley digraph $ \ma…

Expanding phenomena over matrix rings

Yeşim Demiroğlu Karabulut, Doowon Koh, Thang Pham +2

In this paper, we study expanding phenomena in the setting of matrix rings. More precisely, we will prove that If $A$ is a set of $M_{2} (F_{q})$ and $∣ A ∣ ≫ q^{7/2}$ , then we…

Cayley Digraphs of Matrix Rings over Finite Fields

Yeşim Demiroğlu Karabulut

We use the \emph{unit-graphs} and the \emph{special unit-digraphs} on matrix rings to show that every $n \times n$ nonzero matrix over $F_{q}$ can be written as a sum of two $\o…
