On The Hub Number of Some Graphs
Edilberto C. Cuaresma, Rolando N. Paluga · 2016
In this paper, we give the results for the hub numbers of the join and corona of two connected graphs, cartesian product of two complete graphs, cartesian product of a non-complete connected graph and a complete graph and the cartesian product of two paths $P_m$ and $P_n$ for $n\geq 4$ and $m=2,3$. Moreover, we give an upperbound for the hub number of the cartesian product of two paths $P_m$ and $P_n$ for $4\leq m\leq n$.
