Abstract

This paper deals with a problem of lifting of operators in Krein spaces, with minimal signature numbers of the defects. There are obtained necessary and sufficient conditions for the existence of liftings and parametrization formulae for the set of all solutions. As applications there are treated a problem of selfadjoint extensions of symmetric operators and a variant of lifting of commutants.
