It is well known that the Poisson Lie algebra is isomorphic to the Hamiltonian Lie algebra [1],[3],[13]. We show that the Poisson Lie algebra can be embedded properly in the special type Lie algebra [13]. We also generalize the Hamitonian Lie algebra using exponential functions, and we show that these Lie algebras are simple.

We say that a finite dimensional Lie algebra is quasi-reductive if it has a linear form whose stabilizer for the coadjoint representation, modulo the center, is a reductive Lie algebra with a center consisting of semisimple elements. Parabolic subalgebras of a semisimple Lie algebra are not always quasi-reductive (except in types A or C by work of Panyushev). The classification of quasireductiv...

Let g be a finite dimensional, complex, reductive Lie algebra. One says that a symmetric, g-invariant, R(resp. C)-bilinear form on g is a Manin form if and only if its signature is (dimCg, dimCg) (resp. is non degenerate). Recall that a Manin-triple in g is a triple (B, i, i), where B is a real (resp. complex) Manin form and where i, i are real (resp. complex) Lie subalgebras of g, isotropic fo...

We show that the sum of two adjoint orbits in the Lie algebra of an exponential Lie group coincides with the Campbell-Baker-Hausdorff product of these two orbits. Introduction N. Wildberger and others have recently investigated the structure of the hypergroup of the adjoint orbits in relation with the class hypergroup of compact Lie groups. A generalization of the notion of this type of hypergr...

We give an analogue of the classical exponential map on Lie groups for Hopf $*$-algebras with differential calculus. The major difference case is interpretation value map, classically element group. interpretations as states algebra, elements a Hilbert $C^{*} $-bimodule $\frac{1}{2}$ densities and dual algebra. examples complex valued functions $S_{3}$ $\mathbb{Z}$, Woronowicz's matrix quantum ...
