Potential counter-examples to a conjecture on the column space of the adjacency matrix
Attempts to resolve the Akbari-Cameron-Khosrovshahi-conjecture have so far focused on the rank of a matrix. The conjecture claims that there exists a nonzero (0, 1)-vector in the row space of a (0, 1)-adjacency matrix A{\bf{A}} of a graph GG, that is not a copy of any row of A{\bf{A}}. We present a...
