Moreover, the invariants of these extensions are computed.engLie algebras obtained as extensions by derivations of the nilpotent algebra L5,3book parthttp://cisne.sim.ucm.es/record=b3232194~S6*spiopen access514515.1Derivation algebraSemi-direct productSolvable Lie algebraGeometríaTopología1204 Geometría1210 Topología
