The Laplacian matrix of weighted threshold graphs

The Electronic Journal of Linear Algebra
Threshold graphs are generated from one node by repeatedly adding a node that links to all existing nodes or adding a node without links. In the weighted threshold graph, we add a new node in step $i$, which is linked to all existing nodes by a link of weight $w_i$.

On the neighbourhood degree sum-based Laplacian energy of graphs

Kuwait Journal of Science
A useful extension of the Laplacian matrix is proposed here and the corresponding modification of the Laplacian energy (LE) is presented. The neighbourhood degree sum-based Laplacian energy (LNE) is produced by means of the eigenvalues of the newly ...

The Laplacian Spread of a Tree

Discrete Mathematics & Theoretical Computer Science, 2008
The Laplacian spread of a graph is defined to be the difference between the largest eigenvalue and the second smallest eigenvalue of the Laplacian matrix of the graph.

Multi-label feature selection based on dynamic graph Laplacian

Tongxin xuebao, 2020
In view of the problems that graph-based multi-label feature selection methods ignore the dynamic change of graph Laplacian matrix, as well as such methods employ logical-value labels to guide feature selection process and loses label information, a ...
