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 Quantum Spheres and their Embedding into Quantum Minkowski Space-Time
M. Lagraa
We recast the Podles spheres in the noncommutative physics context by showing that they can be regarded as slices along the time coordinate of the different regions of the quantum…
