Some results concerning invertible Morishima and anti-Morishima matrices whose associated digraphs are trees (Q1065029)

Let A be an invertible Morishima matrix whose associated digraph is a tree. In the article the main result gives an answer when matrices A and \(A^{-1}\) will be conformal (anticonformal). In several corollaries the further information concerning the structure of A or \(A^{-1}\) is given.
