On the Coefficients of Hurwitz-Type Matrix Polynomials

Abdon E. Choque-Rivero

Consider the matrix polynomial $f_{n} (z) = I_{q} z^{n} + A_{1} z^{n - 1} + \dots + A_{n},$ where $A_{j} \in C^{q \times q}$ . Write $f_{n} (z) = h_{n} (z^{2}) + z g_{n} (z^{2}) .$ A…

On the Hurwitz Stability of Hurwitz-Type Matrix Polynomials

Abdon E. Choque-Rivero

Every matrix polynomial $f_{n}$ admits a decomposition of the form \[ {\mathbf f}_n(z)={\mathbf h}_n(z^2)+z\,{\mathbf g}_n(z^2). \] The matrix polynomial $f_{2 m}$ …
