AUTHORS ABSTRACTContractive linear relations in Hilbert spaces are (graphs of) operators, but in spaces with an indefinite metric this is not always true. The presence of a multivalued part gives difficulties in the characterization of maximal contractive linear relations and in the proof of the existence of invariant subspaces. These topics are considered in this note. More... »
