Abstract

We determine the signless Laplacian spectrum for the \( H \)-join of regular graphs \( G_1, \ldots, G_p \). We also find an expression and upper bounds for the signless Laplacian spread of the \( H \)-join of regular graphs \( G_1, \ldots, G_p \).

Keywords: signless Laplacian eigenvalues, signless Laplacian spread, graph, regular graph, H-join
