本文研究了一类代数,它的起源是乔治Lusztig的著作[L]. Lusztig引入了一个代数域Q(t)的有理函数在Qin一个indeterminatet,他后来表明是同构的积极部分U+的一个特定的量子群。Lusztig通过结构性质定义了代数。我们在下面(第1节)提出了一个代数范畴L(A,v,I,·),它基于Lusztig的定义off;第2节包含L(A,v,I,·)的一些一般性。在适合于这类范畴的语言中,f可以被刻画为类L(Q(t),t,I,·)的非退化成员(见3.1节)。
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).
