Vertex matrices are graphs showing interconnected concepts or data. These graphs can take a variety of shapes from traditional rows and columns of information to floating bubbles of conceptual ...

Let G be a graph, A(G) be the adjacency matrix of G, and λ(G) the least eigenvalue of A(G). Information is given about the following three quantities: $\lambda_R(G ...

In this paper, we introduce a new simple but powerful general technique for the study of edge- and vertex-reinforced processes with super-linear reinforcement, based on the use of order statistics for ...
