It is shown that the quantized enveloping algebra of s1(n) contains a
generalized Lie algebra, defined by means of axioms similar to Woronow
icz's; This gives rise to Lie algebra-like generators and relations fo
r the locally finite part of the quantized enveloping algebra, and sug
gests a canonical Poincare-Birkhoff-Witt basis. (C) 1998 American Inst
