A Constructive Proof of NC Fejér-Riesz Theorem
arXiv:2207.02174
Abstract
In this paper, we present a constructive proof of Popescu's non-commutative Fejér-Riesz theorem for non-commuting polynomials. We are considering non-commutating polynomial in left-creation and left-annihilation multi-Toeplitz operators.
