    Kannan, M. Rajesh; Pragada, Shivaramakrishna; WANKHEDE, HITESH (Elsevier B.V., 2024-11)
    In 2010, Butler introduced the unfolding operation on a bipartite graph to produce two bipartite graphs, which are cospectral for the adjacency and the normalized Laplacian matrices. In this article, we describe how the ...
