• ON HYPER GOURAVA INDICES AND COINDICES

V. R. KULLI*

Abstract


We introduce the first and second hyper Gourava indices of a graph. Also we propose the first and second hyper Gouava coindices of a graph. In this paper, we determine the first and second hyper-Gourava indices of some standard classes of graphs. Also the first and second hyper Gourava indices of certain nanotubes are determined.


Keywords


hyper-Gourava indices, hyper-Gourava coindices, nanotubes.
