  The article is devoted to the problem of classification of Manin triples up
to weak and gauge equivalence. 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.
