Total Coloring of Dumbbell Maximal Planar Graphs [PDF]

open access: yesMathematics, 2022
The Total Coloring Conjecture (TCC) states that every simple graph G is totally (Δ+2)-colorable, where Δ denotes the maximum degree of G. In this paper, we prove that TCC holds for dumbbell maximal planar graphs.

Total Global Dominator Coloring of Trees and Unicyclic Graphs [PDF]

open access: yesمجلة بغداد للعلوم, 2023
          A total global dominator coloring of a graph  is a proper vertex coloring of  with respect to which every vertex  in  dominates a color class, not containing  and does not dominate another color class.

A decomposition for total‐coloring partial‐grids and list‐total‐coloring outerplanar graphs [PDF]

open access: yesNetworks, 2011
AbstractThe total chromatic number χT(G) is the least number of colors sufficient to color the elements (vertices and edges) of a graph G in such a way that no incident or adjacent elements receive the same color. In the present work, we obtain two results on total‐coloring. First, we extend the set of partial‐grids classified with respect to the total‐

Total Coloring Conjecture for Certain Classes of Graphs [PDF]

open access: yesAlgorithms, 2018
A total coloring of a graph G is an assignment of colors to the elements of the graph G such that no two adjacent or incident elements receive the same color.

Zig-zag facial total-coloring of plane graphs [PDF]

open access: yesOpuscula Mathematica, 2018
In this paper we introduce the concept of zig-zag facial total-coloring of plane graphs. We obtain lower and upper bounds for the minimum number of colors which is necessary for such a coloring.

Total colorings-a survey

open access: yesAKCE International Journal of Graphs and Combinatorics, 2023
The smallest integer k needed for the assignment of k colors to the elements so that the coloring is proper (vertices and edges) is called the total chromatic number of a graph.

Generalized Fractional Total Colorings of Graphs

open access: yesDiscussiones Mathematicae Graph Theory, 2015
Let P and Q be additive and hereditary graph properties and let r, s be integers such that r ≥ s. Then an r/s -fractional (P,Q)-total coloring of a finite graph G = (V,E) is a mapping f, which assigns an s-element subset of the set {1, 2, . . .

2-Quasitotal Fuzzy Graphs and Their Total Coloring [PDF]

open access: yesAdvances in Fuzzy Systems, 2020
Coloring of fuzzy graphs has many real-life applications in combinatorial optimization problems like traffic light system, exam scheduling, and register allocation. The coloring of total fuzzy graphs and its applications are well studied. This manuscript

Equitable total coloring of Cm□Cn [PDF]

open access: yesDiscrete Applied Mathematics, 2009
AbstractThe equitable total chromatic number of a graph G is the smallest integer k for which G has a k-total coloring such that the number of vertices and edges colored with each color differs by at most one. In this paper, we show that the Cartesian product graphs of Cm and Cn have equitable total 5-coloring for all m≥3 and n≥3.
