Construction of New Gyrogroups and the Structure of their Subgyrogroups

S. Mahdavi, A. R. Ashrafi, M. A. Salahshour

Suppose that $G$ is a groupoid with binary operation $\otimes$ . The pair $(G, \otimes)$ is said to be a gyrogroup if the operation $\otimes$ has a left identity, each element $a \in…

Counting the Number of Centralizers of 2-Element Subsets in a Finite Group

A. R. Ashrafi, F. Koorepazan-Moftakhar, M. A. Salahshour

Suppose $G$ is a finite group. The set of all centralizers of $2 -$ element subsets of $G$ is denoted by $2 - C e n t (G)$ . A group $G$ is called $(2, n) -$ centralizer if $∣2 - C e n t (G) ∣ = n$ a…

On a Conjecture about Degree Deviation Measure of Graphs

Ali Ghalavand, Ali Reza Ashrafi

Let G be an n-vertex graph with m edges. The degree deviation measure of G is defined as s(G)=sum v in V(G)|degG(v)-(2m/n)|, where n and m are the number of vertices and edges of G…
