The case of complex simple Lie algebras can be obtained by the papers of A.Belavin, V.Drinfel'd, M.Semenov-Tian-Shanskii. Studing the action of conjugation on complex Manin triples, we get the list of real doubles. We classify all $ad$-invariant forms on the double compatible with bialgebra structure. We classify the Manin triples $(g(R),W,g(C))$ up to weak and gauge equivalence.Latex, 22 pagesQuantum Algebra17B20, 17B37text
