Some remarks about the second Leibniz cohomology group for Lie algebras
Louis Magnin
We compare by a very elementary approach the second adjoint and trivial Leibniz cohomology spaces of a Lie algebra to the usual ones. Examples are given of coupled cocycles. Some p…

Left invariant complex structures on U(2) and SU(2)xSU(2) revisited
Louis Magnin
We compute the torsion-free linear maps from the Lie algebra su(2) into itself, deduce a new determination of the integrable complex structures and their equivalence classes under…
