Augmented eccentric connectivity index of single-defect nanocones
We present explicit formulas for the values of augmented eccentric connectivity indices of single-defect nanocones. Our main result is that the augmented eccentricity index of an $n$-layer nanocone with a single $k$-gonal defect at its apex behaves asymptotically as $27k(1 - \ln 2) n$ for $k \geq 5$.
