@Brendan Foreman: Nice comment. Wouldn't you develop it as an answer?

comment The Jacobi Identity for the Poisson Bracket
@Josè Figueroa-O'Farrill: Thanks for the attention. In my answer, I tried to highlight this point that was already in your answer. But my approach is lowbrow with respect to the highbrow answer of Jonathan.

comment Lie group operation and tangent vectors
About some of following answers: Excuse me, but is not the content of the question exactly to prove that $T_{e,e}\mu(\xi,\eta)=\xi+\eta$ for any $\xi,\eta\in T_eG$? So we should not appeal to it in a proof. But we should point out that this expression is just a consequence of the canonical identification of $T(G\times G)$ with the direct product $TG\times TG$.

comment The Jacobi Identity for the Poisson Bracket
@Josè Figueroa-O'Farrill: When, for an arbitrary almost-symplectic manifold, we again construct the bracket, is correct that $d\omega(X_f,X_g,X_h)$ is equal to the Jacobiator $J(f,g,h)$? or I am making same mistake?

I find your answer to be the right complement to Jose's answer. Thanks.

comment What is a Lagrangian submanifold intuitively?
@Stefan Waldmann: It is remarkable that first occurrences of Lagrangian submanifolds and even of the Fourier integral operators could be found in the pioneer work of Maslov.
