The autoregressive filter problem for multivariable degree one symmetric polynomials

Jeffrey S. Geronimo, Hugo J. Woerdeman, Chung Y. Wong

The multivariable autoregressive filter problem asks for a polynomial $p (z) = p (z_{1}, \dots, z_{d})$ without roots in the closed $d$ -disk based on prescribed Fourier coefficients of i…

Spectral density functions of bivariable stable polynomials

Jeffrey S. Geronimo, Hugo J. Woerdeman, Chung Y. Wong

The relationship between a stable multivariable polynomial $p (z)$ and the Fourier coefficients of its spectral density function $1/∣ p (z) ∣^{2}$ , is further investigated. In this paper…
