Bounds on the General Eccentric Connectivity Index
Symmetry, 2022 The general eccentric connectivity index of a graph R is defined as ξec(R)=∑u∈V(G)d(u)ec(u)α, where α is any real number, ec(u) and d(u) represent the eccentricity and the degree of the vertex u in R, respectively. In this paper, some bounds on the general eccentric connectivity index are proposed in terms of graph-theoretic parameters, namely, order ...

The Connective Eccentricity Index of Hypergraphs
Mathematics, 2022 The connective eccentricity index (CEI) of a hypergraph G is defined as ξce(G)=∑v∈V(G)dG(v)εG(v), where εG(v) and dG(v) denote the eccentricity and the degree of the vertex v, respectively.

Maximum eccentric connectivity index for graphs with given diameter [PDF]
Discrete Applied Mathematics, 2019 The eccentricity of a vertex $v$ in a graph $G$ is the maximum distance between $v$ and any other vertex of $G$. The diameter of a graph $G$ is the maximum eccentricity of a vertex in $G$. The eccentric connectivity index of a connected graph is the sum over all vertices of the product between eccentricity and degree.

Eccentric connectivity index of graphs with subdivided edges
Electronic Notes in Discrete Mathematics, 2014 We consider four classes of graphs arising from a given graph via different types of edge subdivisions. We present explicit formulas expressing their eccentric connectivity index in terms of the eccentric connectivity index of the original graph and some auxiliary invariants.

Minimum eccentric connectivity index for graphs with fixed order and fixed number of pendant vertices [PDF]
Yugoslav Journal of Operations Research, 2019 The eccentric connectivity index of a connected graph G is the sum over all vertices v of the product dG(v)eG(v), where dG(v) is the degree of v in G and eG(v) is the maximum distance between v and any other vertex of G.
