On proper Hamiltonian-connection number of graphs
Sampathkumar, R.; Anantharaman, Selvaraj (Işık University Press, 2022)A graph G is Hamiltonian-connected if every two vertices of G are connected by a Hamilton path. A bipartite graph H is Hamiltonian-laceable if any two vertices from different partite sets of H are connected by a Hamilton ... -
The orientation number of three complete graphs with linkages
Rajasekaran, Ganapathy; Sampathkumar, R. (Işık University Press, 2021)For a graph G, let D(G) be the set of all strong orientations of G. The orientation number of G is d~(G) = min{d(D)|D ? D(G)}, where d(D) denotes the diameter of the digraph D. In this paper, we consider the problem of ... -
Packing colorings of the corona product of the path Pn and the cycle Cn with an edge K₂
Sampathkumar, R.; Sivakaran, T.; Unnikrishnan, R. (Işık University Press, 2026-01-01)Given a graph G and a positive integer i, an i-packing in G is a subset X of V (G) such that the distance dG(u, v) between any two distinct vertices u, v ∈ X is greater than i. The packing chromatic number χρ(G) of a graph ...
