Abstract
We introduce the notion of sign characteristic for selfadjoint meromorphic matrix functions which generalizes this notion for matrix polynomials introduced by the authors in [4]. The purpose of this paper is to show equivalence of various definitions of the sign characteristic for meromorphic matrix functionsKeywords
