Minimal degree rational unimodular interpolation on the unit circle
Electronic transactions on numerical analysis, Tome 30 (2008), pp. 88-106
We consider an interpolation problem with distinct nodes and interpolation values $\textcent \sterling $########

${\S}$

###$\copyright \ddot \copyright \ddot \ddot \copyright $###$\sterling \textcent $ , all on the complex unit circle, and seek interpolants of minimal degree in the class consisting of ######$\ddot \ddot \copyright \ddot $###$ \sterling $! ratios of finite Blaschke products. The focus is on the so-called damaged cases where the interpolant of minimal degree is non-uniquely determined. This paper is a continuation of the work in Glader [Comput. Methods Funct.
