Fast stability tests for Hermitian matrix polynomials
Vanni Noferini, Xuzhou Zhan
Assessing the asymptotic stability of linear self-adjoint homogeneous systems of differential-algebraic equations requires testing the Hurwitz stability of the associated Hermitian…

A generalized Hurwitz stability criterion via rectangular block Hankel matrices for nonmonic matrix polynomials
Zixiang Ni, Yongjian Hu, Xuzhou Zhan
We develop a Hurwitz stability criterion for nonmonic matrix polynomials via column reduction, generalizing existing approaches constrained by the monic assumption and thus serving…
