Yu.Ⅰ.Manin[5]在范畴上引入各种代数结构,但没有进行深入的研究.本文在三角Hopf代数的表示范畴上进行系统的研究,在此范畴上的Lie代数与Hopf代数之间建立了重要的联系,主要结果有:(1)三角Hopf代数表示范畴上Lie代数的包络代数是此范畴上的Hopf代数;(2)三角Hopf代数表示范畴上Lie双代数结构可唯一扩张为其包络代数的余Poisson-Hopf代数结构.因而推广了M.E.Sweedler的经典结果与V.G.Drinfeld的一个重要定理. 相似文献

在[8]中,作者讨论余循环交叉积和扭积之间的关系(见定理 5.3).设 A#XH为余循环交叉积,r∈Hom(H,A),是卷积可逆的,且r(1)=1.在][6]中,S.Majid对任意地余循环X定义了余同调变换 xr·在本文中,首先证明了[8]中的定理 5.3以及它的对偶在一般情况下成立. S. Majid在[5]中给出了余循环交叉积和余循环交叉余积形成双代数的充要条件,这种结构称为Bicrossproduct积.这里讨论了余循环余同调变换如何具体地保持这种双代数结构. 相似文献

本文首先利用cointegral和cocleft模余代数概念,得到H为Hopf代数当且仅当H作为H-模余代数是cocleft以及模余代数的一些性质.然后,设C为H-模余代数.令C=C/Ckerε则有.最后,证明了结构定理:当C为cocleftH-模余代数时,作为余代数有同构:C≌C×H 相似文献

Hom-structures (Lie algebras, algebras, coalgebras, Hopf algebras) have been investigated in the literature recently. We study Hom-structures from the point of view of monoidal categories; in particular, we introduce a symmetric monoidal category such that Hom-algebras coincide with algebras in this monoidal category, and similar properties for coalgebras, Hopf algebras, and Lie algebras. 相似文献

In this paper,we first give a direct sum decomposition of Lie comodules,and then accord- ing to the Lie comodule theory,construct some(triangular)Lie bialgebras through Lie coalgebras. 相似文献

We characterize hereditary (as coalgebras) Hopf algebras by the property of ‘equivariant smoothness’, and apply the result
to generalize to the super-context, the category equivalence, due to Hochschild, between the unipotent algebraic affine groups
and the finite-dimensional nilpotent Lie algebras, in characteristic zero. The global dimension of commutative Hopf algebras,
regarded as coalgebras, is also discussed.

Given an (H,R)-Lie coalgebra Γ, we construct (H,R T )-Lie coalgebra ΓT through a right cocycle T, where (H,R) is a triangular Hopf algebra, and prove that there exists a bijection between the set of (H,R)-Lie coalgebras and the set of ordinary Lie coalgebras. We also show that if (L, [, ], Δ, R) is an (H,R)-Lie bialgebra of an ordinary Lie algebra then (L T , [, ], ΔT, R T ) is an (H,R T )-Lie bialgebra of an ordinary Lie algebra. 相似文献

This survey considers work published between 1970 and 1990 on the algebraic aspects of Hopf theory. There are detailed discussions of the properties of antipodes, group and primitive elements, integrals, crossed products, Galois theory, Lie coalgebras, the category of Hopf algebras, quantum groups, etc.Translated from Itogi Nauki i Tekhniki, Seriya Algebra, Topologiya, Geometriya, Vol. 29, pp. 3–63, 1991. 相似文献

In this work, we introduce a new concept which is obtained by defining a new compatibility condition between Lie algebras
and Lie coalgebras. With this terminology, we describe the interrelation between the Killing form and the adjoint representation
in a new perspective. 相似文献

We show that the basic notions of the locally analytic representation theory can be reformulated in the language of topological coalgebras (Hopf algebras) and comodules. We introduce the notion of admissible comodule and show that it corresponds to the notion of admissible representation in the case of compact p-adic group. 相似文献

In this article, we construct a lot of new examples of Hopf group coalgebras by considering Majid's bicrossproduct Hopf algebra in Turaev category. Furthermore, we find the sufficient and necessary conditions for such Majid's bicrossproduct Hopf algebra to admit quasitriangular structures in the sense of Turaev group coalgebras. 相似文献
