This paper is concerned with a class of algebras whose origin is in George Lusztig’s book [L]. Lusztig introduces an algebrafover the fieldQ(t) of rational functions overQin an indeterminatet, which he shows later is isomorphic to the positive part U+of a certain quantum group. Lusztig defines the algebrafby structural properties. We propose below (Section 1) a categoryL(A, ν, I, ·)of algebras which is based on Lusztig’s definition off; Section 2 contains some generalities onL(A, ν, I, ·). In language appropriate to such categories,fmay be characterized as a non-degenerate member of the classL(Q(t), t, I, ·)(see §3.1).
