A Survey on Reproducing Kernel Krein Spaces
Aurelian Gheondea
This is a survey on reproducing kernel Krein spaces and their interplay with operator valued Hermitian kernels. Existence and uniqueness properties are carefully reviewed. The appr…

Triplets of Closely Embedded Hilbert Spaces
Petru Cojuhari, Aurelian Gheondea
We obtain a general concept of triplet of Hilbert spaces with closed (unbounded) embeddings instead of continuous (bounded) ones. The construction starts with a positive selfadjoin…

An Interpolation Problem for Completely Positive Maps on Matrix Algebras: Solvability and Parametrisation
Calin-Grigore Ambrozie, Aurelian Gheondea
We present certain existence criteria and parameterisations for an interpolation problem for completely positive maps that take given matrices from a finite set into prescribed mat…
