The Minimal and Characteristic Polyanalytic Polynomials of a Normal Matrix

The concept of the minimal polyanalytic polynomial was introduced by M. Huhtanen in connection with the generalized Lanczos process as applied to a normal matrix. The paper discusses the possibility of finding an equivalent of the characteristic polynomial in the set of polyanalytic polynomials. © 2018, Springer Science+Business Media, LLC, part of Springer Nature.
