Let U be the quantised enveloping algebra associated to a finite-type w x w x root datum, as defined by Drinfeld 10 and Jimbo 17 , and modified by w x w y1 x Ž . Lusztig 24 . Put A A s ޚ q, q . In the first instance U is a ޑ q -algebra; by analogy with the Kostant -ޚform of the classical enveloping algebra, w x Lusztig 23 has defined an A A-form U in U. By base change we obtain an * Part of this work was carried out while the author was employed at Bristol University.
