Convertible Subspaces of Hessenberg-Type Matrices

Convertible Subspaces of Hessenberg-Type Matrices

We describe subspaces of generalized Hessenberg matrices where the determinant is convertible into the permanent by affixing ± signs. An explicit characterization of convertible Hessenberg-type matrices is presented. We conclude that convertible matrices with the maximum number of nonzero entries ca...
