Abstract

Stability Terminology resultant valued matrix polynomials Prediction theory Mathematics Intersecting zeros Cayley-Bacharach Filters FejÉr-Riesz factorization Schur-Cohn Density functional theory Polynomials spectral factorization
In order to construct two-variable polynomials with a certain zero behavior, the notion of intersecting zeros is studied. We show that generically two-variable polynomials have a finite set of intersecting zeros, and give an algorithm on how to construct a polynomial with the desired intersecting zeros. Relations with the Cayley-Bacharach theorem are addressed. In addition, we will also address the case when stable polynomials are sought.
