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 ... -
Tight just excellent graphs
Mudartha, Irene Kulrekha; Sundareswaran, Raman; Swaminathan, Venkatasubramanian (Işık University Press, 2019)A graph G is χ-excellent if for every vertex v, there exists a chromatic partition π such that {v} ∈ π.A graph G is just χ-excellent if every vertex appears as a singleton in exactly one χ-partition. In this paper, a special ...
