Boundary-weighted barycenter spaces
Mohameden Ahmedou, Sadok Kallel
We study boundary-weighted barycenter spaces, in which an interior support point has cost (or weight) two and a boundary support point has cost one. These spaces are finite-dimensi…
Higher-Dimensional Anyons via Higher Cohomotopy
Sadok Kallel, Hisham Sati, Urs Schreiber
We highlight that integer Heisenberg groups at level 2 underlie topological quantum phenomena: their group algebras coincide with the algebras of quantum observables of abelian any…
Constrained polynomial roots and a modulated approach to Schur stability
Ziyad AlSharawi, Jose S. Cánovas, Sadok Kallel
It is common in stability analysis to linearize a system and investigate the spectrum of the Jacobian matrix. This approach faces the challenge of determining the matrix spectrum w…
Global stability in the Ricker model with delay and stocking
Ziyad AlSharawi, Sadok Kallel
We consider the Ricker model with delay and constant or periodic stocking. We found that the high stocking density tends to neutralize the delay effect on stability. Conditions are…
Configuration Spaces of Points: A User's Guide
Sadok Kallel
This user's guide (updated version) consists of two parts. The first part is an extensive survey contributed to the Encyclopedia of Mathematical Physics, 2nd edition. It covers man…
Attractors in -dimensional discrete systems of mixed monotonicity
Ziyad AlSharawi, Jose S. Cánovas, Sadok Kallel
We consider -dimensional discrete-time systems of the form in which the map is continuous and monotonic in each one of its arguments. We de…
