Some remarks on Nichols algebras

open access: yes, 2003
Two algebras can be attached to a braided vector space $(V, c)$ in an intrinsic way; the FRT-bialgebra and the Nichols algebra $\toba(V, c)$. The FRT-bialgebra plays the r le of the algebra of quantum matrices, whereas the r le of the Nichols algebra is less understood. Some authors call $\toba(V)$ a quantum symmetric algebra.

Reflection of Nichols Algebras over Coquasi-Hopf Algebras

open access: yes
This paper extends the foundational reflection theory of Nichols algebras to the setting of some certain coquasi-Hopf algebras. Our primary motivation arises from the classification of pointed finite-dimensional coquasi-Hopf algebras. We develop a reflection theory for tuples of simple Yetter-Drinfeld modules in the category $\GG$, where $G$ is a ...

Nichols algebras of U_q(g)-modules

open access: yes, 2004
A technique is developed to reduce the investigation of Nichols algebras of integrable U_q(g)-modules to the investigation of Nichols algebras of braided vector spaces with diagonal braiding. The results are applied to obtain information on the Gelfan'd-Kirillov dimension of these Nichols algebras and their defining relations if the braiding is of a ...

On Nichols algebras of low dimension

open access: yes, 2000
This is a contribution to the classification program of pointed Hopf algebras. We give a generalization of the quantum Serre relations and propose a generalization of the Frobenius-Lusztig kernels in order to compute Nichols algebras of diagonal group type.
