Abstract :
In this article, the hubtic number of the join and corona of two connected
graphs is computed. The restrained hubtic number ξr(G) of a graph G is the maximum
number such that we can partition V (G) into pairwise disjoint restrained hub sets. We
compute the restrained hubtic number of some standard graphs. Some bounds for ξr(G)
are obtained.
