The Gourava Indices and Coindices of Graphs

We introduce the first and second Gourava indices of a molecular graph. Also we introduce the first and second Gourava coindices of a molecular graph. In this paper, we compute the first and second Gourava indices of some standard classes of graphs. We also compute the first and second Gourava indices of armchair polyhex and zigzag-edge polyhex nanotubes.
