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 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…
