In this paper, we investigate when the unit, unitary and total graphs are ring graphs, and also we study

the case that they are outerplanar.

In this paper, we investigate when the unit, unitary and total graphs have

planar line graph, and also we study the case when these line graphs are ring graph or

outerplanar.

Let R be a ring with the identity element 1, α be an endomorphism of R and b be a

left α-derivation. In this paper, we introduce a generalization of a commuting graph,

which is denoted by ΓR(α, b), as a ...

In this paper, we associate a simple graph to a lattice L, in which the vertex

set is being the set of all elements of L, and two distinct vertices x and y are adjacent

if x ∨ y ∈ S, when S is a multiplicatively ...
