A Variational Principle for Linear Pencils of Forms,Eigenvalues are characterized by a double extremum principle for pencils . under rather weak assumptions on the symmetric sesquilinear forms . and .. For example, they can be indefinite and/or degenerate. The treatment unifies many cases previously studied separately, and also gives new eigenvalues previously uncharacterized.

The Spectrum of the Multiplication Operator Associated with a Family of Operators in a Banach SpaceAn operator family of densely defined closed linear operators and the multiplication operator associated with it are considered. The spectrum of this multiplication operator is expressed in terms of the spectra of the operators in the given family.

A Factorization Model for the Generalized Friedrichs Extension in a Pontryagin Space,An operator model for the generalized Friedrichs extension in the Pontryagin space setting is presented. The model is based on a factorization of the associated Weyl function (or .-function) and it carries the information on the asymptotic behavior of the Weyl function at . = ∞.
