Abstract:
We study analytic properties of special classes of matrix functions (locally definitizable and locally Nevanlinna functions) by methods of operator theory. The aim of this paper is to prove that if $G(\lambda)$ is a locally definitizable or locally generalized matrix Nevanlinna function, then $-(G(\lambda))^{-1}$ belongs to the same class.
Keywords:
Krein space, meromorphic function, definitizable operator-function, Nevanlinna matrix-function, generalized resolvent.
