Chromatic weak domatic partition in graphs
Aristotle, Panneerselvam; Balamurugan, Solayappan; Selva Lakshmi, P.; Swaminathan, Venkatasubramanian (Işık University Press, 2019)In a simple graph G, a subset D of V (G) is called a chromatic weak dominating set if D is a weak dominating set and χ(< D >) = χ(G). Similar to domatic partition, chromatic weak domatic partition can be defined. The maximum ... -
Computational complexity of domination integrity in graphs
Sundareswaran, Raman; Swaminathan, Venkatasubramanian (Işık University Press, 2015)In a graph G, those dominating sets S which give minimum value for |S| + m(G?S), where m(G?S) denotes the maximum order of a component of G?S, are called dominating integrity sets of G (briefly called DI-sets of G). This ... -
Distance majorization sets in graphs
Sundareswaran, Raman; Swaminathan, Venkatasubramanian (Işık University Press, 2015)Let G = (V, E) be a simple graph. A subset D of V (G) is said to be a distance majorization set (or dm - set) if for every vertex u ? V ? D, there exists a vertex v ? D such that d(u, v) ? deg(u) + deg(v). The minimum ... -
Global color class domination partition of a graph
Swaminathan, Venkatasubramanian; Praba, Venkatrengan (Işık University Press, 2019)Color class domination partition was suggested by E. Sampathkumar and it was studied in [1]. A proper color partition of a finite, simple graph G is called a color class domination partition (or cd-partition) if every color ... -
Integrity and domination integrity of gear graphs
Sundareswaran, Raman; Swaminathan, Venkatasubramanian (Işık University Press, 2016-06-30)C.A. Barefoot, et. al. [4] introduced the concept of the integrity of a graph. It is an useful measure of vulnerability and it is defined as follows. I(G) = min{|S| + m(G ? S) : S ? V (G)}, where m(G ? S) denotes the order ... -
Tight just excellent graphs
Mudartha, Irene Kulrekha; Sundareswaran, Raman; Swaminathan, Venkatasubramanian (Işık University Press, 2019)A graph G is ?-excellent if for every vertex v, there exists a chromatic partition ? such that {v} ? ?.A graph G is just ?-excellent if every vertex appears as a singleton in exactly one ?-partition. In this paper, a special ...
