Some constructions of multiplicative -ary Hom-Nambu algebras
Abdelkader Ben Hassine, Sami Mabrouk, Othmen Ncib
We show that given a Hom-Lie algebra one can construct the n-ary Hom-Lie bracket by means of an (n-2)-cochain of given Hom-Lie algebra and find the conditions under which this n-ar…
On the ascent-descent spectrum
Nassim Athmouni, Mondher Damak, Chiraz Jendoubi
We establish the various properties as well as diverse relations of the ascent and descent spectra for bounded linear operators. We specially focus on the theory of subspectrum. Fu…
Corwin-Greenleaf multiplicity function for compact extensions of the Heisenberg group
Majdi Ben Halima, Anis Messaoud
Let be the -dimensional Heisenberg group and a closed subgroup of acting on by automorphisms such that is a Gelf…
Global rational stabilization of a class of nonlinear time-delay systems
Nadhem Echi, Boulbaba Ghanmi
The present paper is mainly aimed at introducing a novel notion of stability of nonlinear time-delay systems called Rational Stability. According to the Lyapunov-type, various suff…
Observer design and practical stability of nonlinear systems under unknown time-delay
Nadhem Echi
In the present paper, we study observer design and we establish some sufficient conditions for practical exponential stability for a class of time-delay nonlinear systems written i…
The Binary -Invariant Differential Operators On Weighted Densities On The Superspace And -Relative Cohomology
Khaled Basdouri, Salem Omri, Wissal Swilah
We consider the module structure on the spaces of differential bilinear operators acting on the superspaces of weighted densities. We classify $\mathfrak{aff}…
