Abstract

We study integrable systems on double Lie algebras in absence of Ad-invariant bilinear form by passing to the semidirect product with the τ\tau -representation. We show that in this stage a natural Ad-invariant bilinear form does exist, allowing for a straightforward application of the AKS theory, and giving rise to Manin triple structure, thus bringing the problem to the realm of Lie bialgebras and Poisson-Lie groups.
