Abstract

By a method that already has been introduced by Eliasi and Taeri, we computed the diameter of zigzag polyhex nanotubes. As a consequence of calculating, the reverse Wiener index and reciprocal complementary Wiener index of zigzag polyhex nanotorus were computed. We expressed the results in terms of Gamma function, to help us use the software to speed up calculations. Finally, we obtain these indices for some numerical values.

Keywords: Wiener index, reverse Wiener index, reciprocal complementary Wiener index, nanotorus
