| Abstract: | By elementary transformation of a matrix, we compute the Seidel polynomial of complete 5-partite graph, and give a necessary and sufficient condition for a complete 5-partite graph to be an S-integral graph. Furthermore, we characterize the Seidel spectra of a complete regular 5-partite graph and two classes of complete 5-partite graphs with special structure, respectively. |
