Perturbation of Schauder frames and besselian Schauder frames in Banach spaces
Samir Kabbaj, Rafik Karkri, Hicham Zoubeir
We consider the stability of Schauder frames and besselian Schauder frames under perturbations. Our results are inspirit close to the results of Heil [18].
On *-fusion frames for Hilbert C*-modules
Nadia Assila, Samir Kabbaj, Hicham Zoubeir
Our main goal in this paper, is to generalize to Hilbert C*-modules the concept of fusion frames. Indeed we introduce the notion of *ñfusion frames associated to weighted sequences…
On characterizations of a some classes of Schauder frames in Banach spaces
Rafik Karkri, Samir Kabbaj, Hamad Sidi Lafdal
In this paper, we prove the following results. There exists a Banach space without basis which has a Schauder frame. There exists an universal Banach space (resp. )…
Pairs of Woven continuous frames in Hilbert spaces
Hafida Massit, Mohamed Rossafi, Samir Kabbaj
In this present paper we introduce weaving Hilbert space frames in the continuous case, we give new approaches for manufacturing pairs of woven continuous frames and we obtain new…
--frames for Hilbert spaces and the -adjoint operator
Chaimae Mezzat, Samir Kabbaj, Abdelkarim Bourouihia
In this paper, we will generelize -frames; a new concept of frames for Hilbert spaces, by --frames. The idea is to take a sequence from a Banach space and see how it can b…
On a class of Schauder frames in Banach spaces
Samir Kabbaj, Rafik Karkri, Zoubeir Hicham
In this paper, we give a characterization and a some properties of a besselian sequences, which allows us to build some examples of a besselian Schauder frames. Also for a reflexiv…
