Abstract
The Kronecker polynomial is a finite product of cyclotomic polynomials . Any Kronecker polynomial of degree with simple roots on the unit circle generates a finite set of polynomials (para) orthogonal on the unit circle (POPUC). This set is determined uniquely by the condition . Such set can be called the set of Sturmian Kronecker POPUC. We present several new explicit examples of such POPUC. In particular, we define and analyze properties of the Sturmian cyclotomic POPUC generated by the cyclotomic polynomials . Expressions of these polynomials strongly depend on the decomposition of into prime factors.
