The Laplacian matrix in chemistry

Journal of Chemical Information and Computer Sciences, 1994
The Laplacian matrix, its spectrum, and its polynomial are discussed. An algorithm for computing the number of spanning trees of a polycyclic graph, based on the corresponding Laplacian spectrum, is outlined. Also, a technique using the Le Verrier-Faddeev-Frame method for computing the Laplacian polynomial of a graph is detailed.

On Determinant of Laplacian Matrix and Signless Laplacian Matrix of a Simple Graph

2017
In a simple graph, Laplacian matrix and signless Laplacian matrix are derived from both adjacency matrix and degree matrix. Although, determinant of Laplacian matrix is always zero, yet we express it using only the adjacency matrix and square of its adjacency matrix.

Orthogonal Eigenvector Matrix of the Laplacian

2015 11th International Conference on Signal-Image Technology & Internet-Based Systems (SITIS), 2015
The orthogonal eigenvector matrix Z of the Laplacian matrix of a graph with N nodes is studied rather than its companion X of the adjacency matrix, because for the Laplacian matrix, the eigenvector matrix Z corresponds to the adjacency companion X of a regular graph, whose properties are easier.

Conjugate Laplacian matrices of a graph

Discrete Mathematics, Algorithms and Applications, 2018
Let [Formula: see text] be a simple graph of order [Formula: see text] Let [Formula: see text] and [Formula: see text] where [Formula: see text] and [Formula: see text] are two nonzero integers and [Formula: see text] is a positive integer such that [Formula: see text] is not a perfect square.
