講演概要:
The Nevanlinna-Pick interpolation problem (NPIP) leads naturaly to a chain of linear rational transformations which generate a continued fraction of R-II type. In turn, this continued fraction generate a set of biorthogonal rational functions. In case of the NPIP these biorthogonal functions are in fact orthogonal with respect to the ordinary scalar product.
