Primitive Cohomology of Hopf algebras
D. -G. Wang, J. J. Zhang, G. Zhuang
Primitive cohomology of a Hopf algebra is defined by using a modification of the cobar construction of the underlying coalgebra. Among many of its applications, two classifications…
Connected Hopf algebras of Gelfand-Kirillov dimension four
D. -G. Wang, J. J. Zhang, G. Zhuang
We classify connected Hopf algebras of Gelfand-Kirillov dimension 4 over an algebraic closed field of characteristic zero.
Coassociative Lie algebras
D. -G. Wang, J. J. Zhang, G. Zhuang
A coassociative Lie algebra is a Lie algebra equipped with a coassociative coalgebra structure satisfying a compatibility condition. The enveloping algebra of a coassociative Lie a…
Hopf algebras of GK-dimension two with vanishing Ext-group
D. -G. Wang, J. J. Zhang, G. Zhuang
We construct and study a family of finitely generated Hopf algebra domains of Gelfand-Kirillov dimension two such that $\Ext^1_H(k,k)=0$. Consequently, we answer a question of…
Lower bounds of Growth of Hopf algebras
D. -G. Wang, J. J. Zhang, G. Zhuang
Some lower bounds of GK-dimension of Hopf algebras are given.
