โฆ Synopsis
Let g,, be a real Lie algebra and g its complexification. The aim of this paper is to study the Lie-CRstructures (in the following we shall call them just LCR-structures) on g,. To an LCR-structure corresponds a CR-structure on the associated real Lie group Go for which right and left translations are both CR-maps. Levi-Mal'cev decomposition permits to consider separately the semisimple and the solvable cases and to describe completely the LCR-structures of a generic real Lie algebra g,. Hence, we introduce and describe the semidirect sum by the adjoint derivation of the structures induced on the solvable radical and on a Levi subalgebra.
