%0 Journal Article %T Imbedding of Lie triple systems into Lie algebras %A Oleg Smirnov %J Mathematics %D 2009 %I arXiv %X We show that the category of Lie triple systems is equivalent to the category of Lie algebras graded by Z/(2Z) such that the odd component generates the algbera and the second graded cohomology group coefficients in any trivial module is zero. As a corollary we obtain an analogous result for symmetric spaces and Lie groups. %U http://arxiv.org/abs/0906.1170v1
