Nonsingular (Vertex-Weighted) Block Graphs

Ranveer Singh, Cheng Zheng, Naomi Shaked-Monderer +1

A graph $G$ is \emph{nonsingular (singular)} if its adjacency matrix $A (G)$ is nonsingular (singular). In this article, we consider the nonsingularity of block graphs, i.e., graphs…

Nonsingular Block Graphs: An Open Problem

Ranveer Singh, Cheng Zheng, Naomi Shaked-Monderer +1

A block graph is a graph in which every block is a complete graph. Let $G$ be a block graph and let $A (G)$ be its (0,1)-adjacency matrix. Graph $G$ is called nonsingular (singular)…
