Exploring graph energies of k-copies of complete graph Kn with a common vertex

Résumé

In this study, we have calculated the energy, Seidel energy, and distance energy for k-copies of
the complete graph Kn, where the graphs share a single common vertex. Additionally, we derived expressions
for the Laplacian energy, Laplacian distance energy, and Laplacian Seidel energy for these graphs. To facilitate
these computations, we also developed a Python code that generates the corresponding energy values.
