On the ADHM construction of noncommutative U(2) k-instanton
M. Lagraa
The basic objects of the ADHM construction are reformulated in terms of elements of the algebra of the noncommutative space. This new formulation of the ADHM con…

The flux of noncommutative U(1) instanton through the fuzzy spheres
A. A. Henni, M. Lagraa
From the ADHM construction on noncommutative we investigate different U(1) instanton solutions tied by isometry trasformations. These solutions present a form of vector fie…

The Boosts in the Noncommutative Special Relativity
M. Lagraa
From the quantum analog of the Iwasawa decomposition of group and the correspondence between quantum and Lorentz groups we deduce the different properties of th…

Measurability of observables in the noncommutative special relativity
M. Lagraa
We adapt the axioms of the quantum mechanics to the quantum Minkowski space-time coordinates and their transformations under the quantum Lorentz group to show how we can formulate…
