Gourava Indices and Hyper-Gourava Indices of Line Graph of HAC5C6C7 Carbon Nanotube

N. K. Raut

Abstract: The first Gourava index GO₁(G) is defined as sum (d_u+d_v) + d_ud_v for all edges uv in the graph, while the first hyper-Gourava index HGO₁(G) squares this sum. In this paper first, second Gourava indices, first and second hyper-Gourava indices of L(HAC₅C₆C₇), T(G), some transformation graphsG^xy, G^xyz and their complements of L(HAC₅C₆C₇) are studied.

Keywords: Gourava index, hyper-Gourava index, line graph, line vertex degree, point vertex degree, transformation graph
