| Abstract: | We report lower and upper bounds for the Harary index of a connected (molecular) graph, and, in particular, upper bounds of
triangle- and quadrangle-free graphs. We also give the Nordhaus–Gaddum-type result for the Harary index.
Dedicated to the memory of Professor Frank Harary (1921–2005), the late grandmaster of both graph theory and chemical graph
theory. |
