On the distance spectral gap and construction of D-equienergetic graphs

Haritha T, Chithra A.

Let denote the distance matrix of a connected graph with vertices. The distance spectral gap of a graph is defined as , where and $ρ_2…

Resistance distance and Kirchhoff index in central vertex join and central edge join of two graphs

Haritha T, Chithra A

The central graph of a graph is the graph obtained by inserting a new vertex into each edge of exactly once and joining all the non-adjacent vertices in . Let $G_…

A study on -coalescence of two graphs

Najiya V K, Chithra A

The -coalescence of two graphs is obtained by merging a -clique of each graph. The -matrix of a graph is the convex combination of its degree matrix and adjacency matrix…

Construction of non-regular -cospectral graphs from some join of graphs

Najiya V K, Chithra A

Cospectral graphs are a fascinating concept in graph theory, where two non-isomorphic graphs possess identical sets of eigenvalues. In this paper, we compute the -characterist…
