Bases of quantized enveloping algebras

Bangming Deng and Jie Du

Vol. 220 (2005), No. 1, 33–48
Abstract

We give a systematic description of many monomial bases for a specified quantized enveloping algebra and of many integral monomial bases for the associated Lusztig [v,v1]-form. The relations among monomial bases, PBW bases and canonical bases are also discussed.

Keywords
quantized enveloping algebra, Ringel–Hall algebra, generic extension, monomial basis, canonical basis
