THE SUBSPACE NEVANLINNA INTERPOLATION PROBLEM AND THE MOST POWERFUL UNFALSIFIED MODEL

摘要

A generalization of the tangential Nevanlinna interpolation problem will be studied from a behavioral point of view. Necessary and sufficient conditions for its solvability and a characterization of art its solutions are derived. These results are obtained by associating to the interpolation data a behavior that enjoys a special structure. (C) 1997 Elsevier Science B.V. [References: 16]
