Let R be a commutative ring with unity 1 ≠ 0 and let R× be the set of all unit elements of R. The unitary Cayley graph of R, denoted by GR = Cay(R, R×), is a simple graph whose vertex set is R and there is an edge between two distinct vertices x

Autor: Afkhami M., Khashyarmanesh K., Shahsavar F.

Publikováno v: Discussiones Mathematicae - General Algebra and Applications, Vol 40, Iss 1, Pp 105-117 (2020)

Let (P, ≤) be a poset with the least element 0. The intersection graph of ideals of P, denoted by G(P), is a graph whose vertices are all nontrivial ideals of P and two distinct vertices I and J are adjacent if and only if I ∩ J ≠ {0}. In this
