Se definen marcos unitariamente equivalentes en espacios de Hilbert con W-métricas, y se da una caracterización de ellos comparando sus respectivos operadores de análisis. A partir de un espacio de Hilbert con un marco se construye un espacio de H

We introduce a concept of approximately invertible elements in non-unital normed algebras which is, on one side, a natural generalization of invertibility when having approximate identities at hand, and, on the other side, it is a direct extension of

In this paper the hyponormal operators on Krein spaces are introduced. We state conditions for the hyponormality of bounded operators focusing, in particular, on those operators $T$ for which there exists a fundamental decomposition $\mathbb{K}= \mat

The purpose of this paper is to propose a definition of continuous frames of rank n for Krein spaces and to study their basic properties. Similarly to the Hilbert space case, continuous frames are characterized by the analysis, the pre-frame and the

The separately radial Fock-Carleson type measures for derivatives of order k are introduced and characterized on the Fock space. Also, we study the separately radial Toeplitz operators generated by derivatives of k-FC type measure and give a criterio

We introduce the so-called horizontal Toeplitz operators acting on the Fock space and give an explicit description of the C*-algebra generated by them. We show that any Toeplitz operator with $$L_{\infty }$$ -symbol, which is invariant under imaginar
