The connectivity index 25 years after

Journal of Molecular Graphics and Modelling, 2001
We review the developments following introduction of the connectivity indices as molecular descriptors in multiple linear regression analysis (MLRA) for structure-property-activity studies. We end the review with discussion of results obtained with applications of the variable connectivity index.

On a novel connectivity index

Journal of Mathematical Chemistry, 2009
We present a novel connectivity index for (molecular) graphs, called sum-connectivity index and give several basic properties for this index, especially lower and upper bounds in terms of graph (structural) invariants. It appears that this and the original Randić connectivity index that we call product- connectivity index are highly intercorrelated ...

On Connected Graphs Having the Maximum Connective Eccentricity Index

Journal of Applied Mathematics and Computing, 2021
The connective eccentricity index (CEI) of a connected graph G is defined as $$\xi ^{ee}(G)=\sum _{u\in V_G}[d_G(u)/\varepsilon _G(u)]$$ , where $$d_G(u)$$ and
