Multi-parameter Quantum Groups via Quantum Quasi-Symmetric Algebras

Quantum Algebra 2013-07-05 v1 Representation Theory

Abstract

It is proved that the entire multi-parameter (small-)quantum groups of symmetrizable Kac-Moody algebras can be realized as certain subquotients of the cotensor Hopf algebras. This is an axiomatic construction. Hopf 2-cocycle deformations variation for the construction machinery is described, moreover, the integrable irreducible modules can be constructed using this setting, even available for those in the fundamental alcove at root of unity case.
