A symmetric Lie algebra is defined, following J. Dixmier, to be a Lie algebra 9 with a decomposition g = t ⨁ p such that l is a subalgebra of g,[t, p]⊂p and [p, p] ⊂t. A definition of Cartan subspace of a symmetric Lie algebra is given, and a theory is presented which parallels the standard theory of Cartan subalgebras of Lie algebras, and which generalizes the classical results for real and complex semisimple symmetric Lie algebras.
