Riesz Bases of Root Vectors of Indefinite Sturm-Liouville Problems with Eigenparameter Dependent Bou. We give sufficient conditions under which a basis of each root subspace for this Sturm-Liouville problem can be selected so that the union of all these bases constitutes a Riesz basis of a corresponding weighted Hilbert space.

Bi-dimensional Moment Problems and Regular Dilationsence of a commuting pair (.) of contractions on . having regular dilation such that . Such moment problems are strongly related to the theory of harmonizable and stationary processes. Isometric or unitary solutions are also characterized in terms of the initial data.

Isospectral Vibrating Systems, Part 2: Structure Preserving Transformationsecified and the objective is to generate isospectral families of systems, i.e., systems which reproduce precisely the eigenvalues of the given system together with their multiplicities. Two central ideas are developed and used, namely, standard triples of matrices, and structure preserving transformations.

A Functional Description for the Commutative ,*-algebras of the , ,-classce, presented as a direct sum of a finite-dimensional neutral subspace and a uniformly positive subspace. A relation between these algebras (that in addition are assumed to be commutative) and function spaces of the type .. ∩ .. is established.
