This paper is a continuation of [EK]. We show that the quantization procedure of [EK] is given by universal acyclic formulas
and defines a functor from the category of Lie bialgebras to the category of quantized universal enveloping algebras. We
also show that this functor defines an equivalence between the category of Lie bialgebras over k [[h]] and the category of quantized universal enveloping (QUE) algebras. 相似文献

The first cohomology group of generalized loop Virasoro algebras with coefficients
in the tensor product of its adjoint module is shown to be trivial. The result is used
to prove that Lie bialgebra structures on generalized loop Virasoro algebras are coboundary
triangular. The authors generalize the results to generalized map Virasoro algebras. 相似文献

Solutions of the classical dynamical Yang-Baxter equation on a Lie superalgebra are called super dynamical matrices. A super dynamical matrix satisfies the zero weight condition if
for all
In this paper we classify super dynamical matrices with zero weight. 13.
We discuss the relationship between the representation of an integrable system as an L-A-pair with a spectral parameter and the existence of two compatible Hamiltonian representations of this system. We consider examples of compatible Poisson brackets on Lie algebras, as well as the corresponding integrable Hamiltonian systems and Lax representations. 相似文献

We consider two classes of integrable nonlinear hyperbolic systems on Lie algebras. These systems generalize the principal chiral model. Each system is related to a pair of compatible Lie brackets and has a Lax representation, which is determined by the direct sum decomposition of the Lie algebra of Laurent series into the subalgebra of Taylor series and the complementary subalgebra corresponding to the pair. New examples of compatible Lie brackets are given. 相似文献

In this paper we obtain that every super-Virasoro algebra admits only triangular coboundary Lie super-bialgebra structures
and this is proved mainly based on the computation of derivations from the super-Virasoro algebra to the tensor product of
its adjoint module.

In this paper, all Lie bialgebra structures on the Lie algebras of generalized Witt type are considered. It is proved that, for any Lie algebra W of generalized Witt type, all Lie bialgebras on W are the coboundary triangular Lie bialgebras. As a by-product, it is also proved that the first cohomology group H1(W, W(?)W) is trivial. 相似文献
