A matrix for counting paths in acyclic colored digraphs

Sudip Bera

In this paper, we introduce a matrix $A_{Γ_{k, R}}$ associate with a $k$ -colored acyclic digraph $Γ_{k, R}$ such that $det (A_{Γ_{k, R}})$ enumerates the paths in the digraph…

Existence of a Non-Zero $(0, 1)$ -Vector in the Row Space of Adjacency Matrices of Simple Graphs

Sudip Bera

We look for a non-zero $(0, 1)$ -vector in the row space of the adjacency matrix $A (Γ)$ of a graph $Γ,$ provided $Γ$ has at least one edge. Akbari, Cameron, and Khosrovshahi conject…
