Canonical Differential Equations of Hilbert-Schmidt Type, property that the selfadjoint operators associated to a canonical system have resolvents of Hilbert-Schmidt type in terms of the Hamiltonian . as well as in terms of the associated Titchmarsh-Weyl coefficient.

Normal Matrices in Degenerate Indefinite Inner Product Spaces,ns, the notion of an adjoint is introduced: the adjoint of a matrix is defined as a linear relation which is a matrix if and only if the inner product is nondegenerate. This notion is then used to give alternative definitions of selfadjoint and unitary matrices in degenerate inner product spaces and

A Necessary Aspect of the Generalized Beals Condition for the Riesz Basis Property of Indefinite Sted generalized one hand Beals condition was found for this Riesz basis property. Now using a new criterion of Parfyonov we show that already the old approach gives rise to a necessary and sufficient condition for the Riesz basis property under certain additional assumptions.
