Abstract

In this paper, we suggest conjectures to approximate the values of energy and Estrada index of CNCk[n] nanocones using computational tools. We conjecture that the energy and Estrada index of CNCk[n] nanocones, k 3, can be estimated by the curves(2.56(k-2)+5.12)n1.854+3.87(k-2)+7.717 and (5.21(k-2)+10.41)n1.861+4.585(k-2)1.225+18.85, respectively..

Keywords

Nanocones, Energy, Estrada index.
