On realization of the Kreĭn-Langer class Nκ of matrix-valued functions in Pontryagin spaces

In this paper the realization problems for the Kreĭn–Langer class Nκ of matrix‐valued functions are being considered. We found the criterion when a given matrix‐valued function from the class Nκ can be realized as linear‐fractional transformation of the transfer function of canonical conservative sy...
