Abstract

Let G be a simple, connected molecular graph. Topological indices and Hub Parameters
are very important concepts, having wide applications in Chemistry and Networks, respectively.
The hub degree of any vertex of G is the number of minimal hub sets of G containing
v. In this paper, we introduce hub degree based topological indices and establish general
formulae of those indices for some standard graphs, double star graph, book graph. Further
we determine hub Zagreb indices of Join of two noncomplete graphs and molecular graph of
cycloalkenes.
