Spectral Points of Type $π_{+}$ and Type $π_{-}$ of Closed Operators in Indefinite Inner Product Spaces

Friedrich Philipp, Carsten Trunk

We introduce the notion of spectral points of type $π_{+}$ and type $π_{-}$ of closed operators $A$ in a Hilbert space which is equipped with an indefinite inner product. It is shown t…
