چکیده
|
The leap eccentric connectivity index of $g$ is defined as $$lxi^{c}(g)=sum_{vin v(g)}d_{2}(v|g)e(v|g)$$ where $d_{2}(v|g) $ be the second degree of the vertex $v$ and $e(v|g)$ be the eccentricity of the vertex $v$ in $g$. in this paper, we give some properties of the leap eccentric connectivity index of the graph $g$.
