Functions with a maximal number of finite invariant or internally-1-quasi-invariant sets or supersets
Nizar El Idrissi, Samir Kabbaj
A relaxation of the notion of invariant set, known as -quasi-invariant set, has appeared several times in the literature in relation to group dynamics. The results obtained in t…
On the minimal Sums of sequences in the tensor product of separable Hilbert spaces
Abdelkrim Bourouihiya, Samir Kabbaj
It is known that the tensor product of two sequences, in the tensor product of two separable Hilbert spaces, is a frame if and only if each component of that product is a frame. Th…
On Some Inequalities-Equalities Concerning the continuous generalized Fusion Frame in Hilbert spaces
Nadia Assila, Samir Kabbaj, Ouafaa Bouftouh +1
Continuous generalized fusion frame theory was recently introduced by Rahimi and al. Several equalities and inequalities have been obtained for frame, fusion generalized fusion fra…
Path-connectedness of the intersection of translates of St(n,H)
Nizar El Idrissi, Samir Kabbaj, Brahim Moalige
If is a Hilbert space, the Stiefel manifold is formed by all the independent -tuples in . In this article, we contribute to the topological study of Stiefel man…
