A constrained Nevanlinna-Pick interpolation problem for matrix-valued functions
J. A. Ball, V. Bolotnikov, S. ter Horst
Recent results of Davidson-Paulsen-Raghupathi-Singh give necessary and sufficient conditions for the existence of a solution to the Nevanlinna-Pick interpolation problem on the uni…
