Abstract

Here the basic properties of two classes of (multi-valued) operators between Kreĭn spaces are presented: the symmetric and isometric relations. Both types of multi-valued operators (relations) naturally appear for instance when studying differential equation; for example Sturm–Liouville equations with an indefinite weight.
