This lecture note presents a new method to analyze changes in signals on graphs. This method, called the vertex-frequency analysis, relies on Laplacian matrices to establish connections between vertex ...

The VerTeX typeset scattered graph data rewriter is based on a new graph data format called VerTeX, which parses and generates LaTeX documents from nodes. Current specifications are concerned with how ...

Graph vertex sampling set selection aims at selecting a set of vertices of a graph such that the space of graph signals that can be reconstructed exactly from those samples alone is maximal. In this ...

In this context, the concepts of vertex regularity and total vertex regularity have been informed and some of its properties have been studied. In this regard, a comparative study between vertex ...

Graph Vertex-Coloring Verifier Coloring-verifier is a small program to verify solutions to graph vertex-coloring problems in the context of the DIMACS Computational Challenges.
