A Generalization of Total Graphs
for total graphs. In this paper, we investigate the basic properties of GT^n_U (R^n). Moreover, we study the planarity of the graphs GT^n_U (U), GT^n_U (R^n-U) and GT^n_U (R^n)....
When the unit, unitary and total graphs are ring graphs and outerplanar
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....
When the line graphs of the unit, unitary and total graphs are planar and 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....
Projective Total Graphs of Commutative Rings
Let T(Γ(R)) be the total graph of a commutative ring R, that is, a graph with all elements of R as vertices
and two distinct vertices a and b are adjacent if and only if a+b is a zero-divisor on R. In this paper, we classify all finite rings...
On the genus of graphs associated to a commutative ring
Let T( Gamma(R)) be the total graph of a commutative ring R ,
that is a graph with all elements of R as vertices and two
distinct vertices a and b are adjacent if and only if a+b is
a zero-divisor on R . In this talk...
Total graphs of Polynomial Rings and Rings of fractions
Let R be a commutative ring. The total graph of R, denoted by T(Γ(R)), is a graph
with all elements of R as vertices, and two distinct vertices x, y ∈ R are adjacent if and
only if x + y ∈ Z(R), where Z(R) denotes the set of zero...
