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 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 is a Hilbert space, the non-compact Stiefel manifold consists of independent -tuples in . In this article, we contribute to the topological study of non-comp…
