Abstract: In this short note we provide an extension of the notion of Hessenberg matrix and observe an identity between the determinant and the permanent of such matrices. The celebrated identity due to Gibson involving Hessenberg matrices is consequently generalized.
Keywords: determinant, permanent, Hessenberg matrices, graphs, trees
