Eccentricity energy change of coalescence of graphs due to edge deletion
Anjitha Ashokan, Chithra A
The eccentricity matrix of a graph is obtained from the distance matrix by keeping the largest entries in their row or column, and the remaining entries are replaced by zeros. The…
On the Estrada Index and Spectral Properties of -Uniform Hypergraphs
Liya Jess Kurian, Chithra A.
Various properties of a hypergraph can be explored through its spectrum. In this paper,we estimate the bound for the sum of , largest eigenvalues of a -uniform hy…
The spectrum of the Corona of Hypergraphs
Liya Jess Kurian, Chithra A.
The corona of hypergraphs is an extension of the corona operation applied to graphs. The corona of two hypergraphs is obtained by taking copies of $G_1^…
On the Adjacency and Seidel Spectra of Hypergraphs
Liya Jess Kurian, Chithra A
A hypergraph generalizes the concept of an ordinary graph. In an ordinary graph, edges connect pairs of vertices, whereas in a hypergraph, hyperedges can connect multiple vertices…
Normalized Laplacian spectra of central vertex join and central edge join of graphs
Jahfar T K, Chithra A
In this paper, we compute normalized Laplacian spectra of central graph of a regular graph, central vertex join and central edge join of two regular graphs. Also, we determine thei…
