چکیده: 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 directed graph with vertex set R and, for two distinct
vertices x and y, there is an arc from x to y if and only if xy = α(y)x + b(y). We study
some basic properties of ΓR(α, b). Also, we investigate the planarity and genus of the
graph ΓR(α, 0).
