On the Hamiltonian formalism of the Tetrad-Gravity with fermions
M. H. Lagraa, M. Lagraa
We extend the analysis of the Hamiltonian formalism of the d-dimensional tetrad-connection gravity to the fermionic field by fixing the non-dynamic part of the spatial connection t…
On the Hamiltonian formalism of the tetrad-gravity
Meriem Hadjer Lagraa, Mohammed Lagraa, Nabila Touhami
We present a detailed analysis of the Hamiltonian constraints of the d-dimensional tetrad-connection gravity where the non-dynamical part of the spatial connection is fixed to zero…
On the Generalized Einstein-Cartan Action with Fermions
Meriem-Hadjer Lagraa, Mohammed Lagraa
From the freedom exhibited by the generalized Einstein action proposed in [1], we show that we can construct the standard effective Einstein-Cartan action coupled to the fermionic…
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…
