Moore-Penrose inverses of the signless Laplacian and edge-Laplacian of graphs [PDF]
The signless Laplacian Q and signless edge-Laplacian S of a given graph may or may not be invertible. The Moore-Penrose inverses of Q and S are studied. In particular, using the incidence matrix, we find combinatorial formulas of the Moore- Penrose inverses of Q and S for trees.

Signless Laplacian and normalized Laplacian on the H-join operation of graphs
Discrete Mathematics, Algorithms and Applications, 2014In this paper, we consider a generalized join operation, that is, the H-join on graphs, where H is an arbitrary graph. In terms of the signless Laplacian and the normalized Laplacian, we determine the spectra of the graphs obtained by this operation on regular graphs.
