Abstract

In this paper, we introduce the concept of $k-$hub set and $k-$hub number of a graph. We compute the $k-$hub number for some standard graphs, also we determined the $k-$hub number for corona of two graphs. Some bounds of $k-$hub number are established. Finally we characterize the structure of all graphs for which $h_k(G)=1$.
