The positive part of the quantized universal enveloping algebra of type A_n as a braided quantum group
arXiv:math/9803070
Abstract
A generalized Hopf algebra structure for the positive (negative) part of the Drinfeld-Jimbo quantum group of type A_n is established without make any use of the usual deformation of the abelian part of sl_{n+1}.
