The laplacian matrix of a graph: unimodular congruence
Linear and Multilinear Algebra, 1990This paper gives graph-theoretic conditions that are sufficient for the Laplaceman matrices of two graphs to be congruent by a unimodular matrix.

The Group Inverse of the Laplacian Matrix of a Graph
2018What follows is a short, selective tour of some of the connections between weighted graphs and the group inverses of their associated Laplacian matrices. The presentation below draws heavily from Kirkland–Neumann [11, Ch. 7], and the interested reader can find further results on the topic in that book.

A Geometric Approach to the Laplacian Matrix of a Graph
1993Let G be a finite undirected connected graph with n vertices. We assign to G an (n - 1)-simplex ∑(G) in the point Euclidean (n - 1)-space in such a way that the Laplacian L(G) of G is the Gram matrix of the outward normals of ∑(G). It is shown that the spectral properties of L(G) are reflected by the geometric shape of the Steiner circumscribed ...
