A theorem of Jones and Ruscheweyh states that for any n different points and n values, all from the unit circle, there is a Blaschke product of degree at most n which interpolates the prescribed values at the prescribed nodes.
We present another proof using elements of real algebraic geometry, positive polynomials and Wörmann's Positivstellensatz.
This is a joint work with Sergei Kalmykov.
