On the resistance regular graphs
Haritha T, Chithra A
For a connected graph , its resistance distance matrix is denoted by . A graph is called resistance regular if all the row (or column) sums of are equal. We provide…

On the distance spectrum and distance-based topological indices of central vertex-edge join of three graphs
Haritha T, Chithra A. V.
Topological indices are molecular descriptors that describe the properties of chemical compounds. These topological indices correlate specific physico-chemical properties like boil…
