Robustness of controlled $K$ -Fusion Frame in Hilbert C $^{*}$ -modules under erasures of submodules

Nadia Assila, Samir Kabbaj, Mohamed Otmani

Controlled $*$ -K-fusion frames are generalization of controlled fusion frames in frame theory. In this paper, we propose the notion of controlled $*$ -k-fusions frames on Hilb…

Independence, infinite dimension, and operators

Nizar El Idrissi, Samir Kabbaj

In [Appl. Comput. Harmon. Anal., 46(3):664-673, 2019], O. Christensen and M. Hasannasab observed that assuming the existence of an operator $T$ sending $e_{n}$ to $e_{n + 1}$ for all $…

Intersections of translates of finite-dimensionally valued frame spaces are conditionally slice-full and almost slice-full

Nizar El Idrissi

In recent work, the topology of frame spaces $F_{(X, μ), n}$ has been studied via Stiefel manifolds, revealing in particular a connectedness property for intersections of t…

Path-connectedness and topological closure of some sets related to the non-compact Stiefel manifold

Nizar El Idrissi, Samir Kabbaj, Brahim Moalige

If $H$ is a Hilbert space, the non-compact Stiefel manifold $S t (n, H)$ consists of independent $n$ -tuples in $H$ . In this article, we contribute to the topological study of non-comp…
