On graphs with distance Laplacian eigenvalues of multiplicity n−4

AbstractLet G be a connected simple graph with n vertices. The distance Laplacian matrix [Formula: see text] is defined as [Formula: see text], where [Formula: see text] is the diagonal matrix of vertex transmissions and [Formula: see text] is the distance matrix of G. The eigenvalues of [Formula: s...
