Three-Dimensional Real Affine Lie Groups
T. Aït Aissa, S. El Bourkadi, M. W. Mansouri
We classify all left-invariant real affine connections in dimension three. Our approach reduces the three-dimensional problem to a two-dimensional one by decomposing each left-inva…
Eight-Dimensional Symplectic Nilpotent Lie Groups with Lagrangian Normal Subgroups: A Complete Classification
T. Aït Aissa, M. W. Mansouri
We investigate symplectic nilpotent Lie groups with Lagrangian normal subgroups. We show that there exists a bijection between the isomorphism classes of nilpotent Lie groups with…
Eight-dimensional non completely reducible symplectic Lie algebras
T. Aït Aissa, S. El Bourkadi, M. W. Mansouri +1
A non completely reducible symplectic Lie algebra is a symplectic Lie algebra which cannot be symplectically reduced to the trivial symplectic Lie algebra. Our aim is to provide a…
On solvable complete symplectic Lie algebras
M. Benyoussef, M. W. Mansouri, SM. Sbai
In this paper, we are interested in solvable complete Lie algebras, over the field $\K=\R$ or , which admit a symplectic structure. Specifically, important classes are…
Cosymplectic Jacobi-Jordan Algebras
S. El bourkadi, M. W. Mansouri
We introduce the notion of cosymplectic structure on Jacobi-Jordan algebras, and we state that they are related to symplectic Jacobi-Jordan algebras. We show, in particular, that t…
