A Topological Approach to Nevanlinna–Pick Interpolation
A Topological Approach to Nevanlinna–Pick Interpolation
We study the set of rational solutions of an $(N + 1)$-point Nevanlinna–Pick problem, that has degree bounded by N Based on the invariance of the topological degree of a certain mapping under deformation, we establish that when the $(N + 1)$-point Nevanlinna–Pick problem is solvable, then for any dissipation …
