AbstractA bicovariant calculus of differential operators on a quantum group is constructed in a natural way, using invariant maps from Fun $$(\mathfrak{G}_q )$$ toUqg, given by elements of the pure braid group. These operators—the “reflection matrix”Y≡L+SL− being a special case—generate algebras that linearly close under adjoint actions, i.e. they form generalized Lie algebras. We establish the connection between the Hopf algebra formulation of the calculus and a formulation in compact matrix… 

On quantum Lie algebras and quantum root systems

As a natural generalization of ordinary Lie algebras we introduce the concept of quantum Lie algebras . We define these in terms of certain adjoint submodules of quantized enveloping algebras endowed

On the algebraic structure of differential calculus on quantum groups

Intrinsic Hopf algebra structure of the Woronowicz differential complex is shown to generate quite naturally a bicovariant algebra of four basic objects within a differential calculus on quantum

Quantum Lie Algebras, Their Existence, Uniqueness and q-Antisymmetry

Abstract: Quantum Lie algebras are generalizations of Lie algebras which have the quantum parameter h built into their structure. They have been defined concretely as certain submodules of the

On the construction of unitary quantum group differential calculus

We develop a construction of the unitary type anti-involution for the quantized differential calculus over GL q ( n ) in the case ∣ q ∣ = 1 . To this end, we consider a joint associative algebra of

Quantum Groups, Non-Commutative Differential Geometry and Applications

The topic of this thesis is the development of a versatile and geometrically motivated differential calculus on non-commutative or quantum spaces, providing powerful but easy-to-use mathematical

Covariant differential complexes on quantum linear groups

We consider the possible covariant external algebra structures for Cartan's 1-forms ( Omega ) on GLq(N) and SLq(N). Our starting point is that the Omega realize an adjoint representation of quantum

A notion of quantum matrix (QM-) algebra generalizes and unifies two famous families of algebras from the theory of quantum groups: the RTT-algebras and the reflection equation (RE-) algebras. These

Differential calculus on compact matrix pseudogroups (quantum groups)

The paper deals with non-commutative differential geometry. The general theory of differential calculus on quantum groups is developed. Bicovariant bimodules as objects analogous to tensor bundles

Quantum Lie Algebras and Differential Calculus on Quantum Groups

We review the differential calculus on quantum groups following the approach used by W oronowicz. It leads us to introduce two notions of quantum Lie algebras which we refer to as braided or


We give a pedagogical introduction to the differential calculus on quantum groups by stressing at all stages the connection with the classical case (q→1 limit). The Lie derivative and the contraction

Differential calculus on quantized simple lie groups

Differential calculi, generalizations of Woronowicz's four-dimensional calculus on SUq(2), are introduced for quantized classical simple Lie groups in a constructive way. For this purpose, the

Vector fields on complex quantum groups

Using previous results we construct theq-analogues of the left invariant vector fields of the quantum enveloping algebra corresponding to the complex Lie algebras of typeAn−1,Bn,Cn, andDn. These

Quasitriangular Hopf Algebras and Yang-Baxter Equations

This is an informal introduction to the theory of quasitriangular Hopf algebras and its connections with physics. Basic properties and applications of Hopf algebras and Yang-Baxter equations are

Constant solutions of reflection equations and quantum groups

To the Yang–Baxter equation an additional relation can be added. This is the reflection equation that appears in various places, with or without spectral parameter, e.g., in factorizable scattering

Compact matrix pseudogroups

The compact matrix pseudogroup is a non-commutative compact space endowed with a group structure. The precise definition is given and a number of examples is presented. Among them we have compact

Quantum and braided linear algebra

Quantum matrices A(R) are known for every R matrix obeying the quantum Yang–Baxter equations. It is also known that these act on ‘‘vectors’’ given by the corresponding Zamalodchikov algebra. This

Central extensions of quantum current groups

We describe Hopf algebras which are central extensions of quantum current groups. For a special value of the central charge, we describe Casimir elements in these algebras. New types of generators
