- 47B50 Operators on spaces with an indefinite metric
Abstract :
We consider a singular Sturm-Liouville differential expression with an indefinite
weight function and we show that the corresponding self-adjoint
differential operator in a
Krein space locally has the same spectral properties as a definitizable operator.
Keywords :
Sturm-Liouville operators, Krein spaces, definitizable operators
