利用一些P. V. -与[3]等价。某些部分与以前的不可约或简单情况的分类[1,2]有很大的不同,需要采用新的方法。这一结果揭示了约化预齐次向量空间分类问题的难点。导论. In M. Sato和T. Kimura [1],所有不可约预齐次向量空间(简称不可约P. V.证明了任何不可约P. V.都与2-单P. V.(或与(SL(m)XSL(m)XGL(2),A1 XA 1 XA 1)(m = 2,3))是castling等价的。因此,作为一般情况分类的一个步骤,自然要对所有不可约的2-单P. V进行分类。's.本文对所有2-单P. V.的类型II,并给出他们的完整列表,直到强等价的意义上的定义4,第36页[1]。但是我们需要各种各样的P.

A classification of 2-simple prehomogeneous vector spaces is completed by using some P.V.-equivalences together with [3]. Some part is very different from the previous classification of the irreducible or simple cases [1, 2], and some new method is necessary. This result shows the difficult point of a classification problem of reductive prehomogeneous vector spaces. Introduction. In M. Sato and T. Kimura [1], all irreducible prehomogeneous vector spaces (abbreviated irreducible P.V.'s) are classified up to castling-equivalence, and it is proved that any irreducible P.V. is castling-equivalent to a 2-simple P.V. (or to (SL(m) X SL(m) X GL(2), A1 X A1 X A1) with m = 2,3). Therefore, as a step to a classification of the general case, it is natural to classify all nonirreducible 2-simple P.V.'s. In this paper, we shall classify all 2-simple P.V.'s of type II and give the complete list of them up to strong equivalence in the sense of Definition 4, p. 36 in [1]. However we need various P.V.-equivalences (cf. Propositions 1.7; 1.12; 1.34; 1.36; 1.37, Theorem 1.16 and its Corollary; Corollary 1.26, Definition 1.31, Remark 1.32) to carry out the classification, and hence, first we shall prove them. We also investigate the regularity in some cases. Since all 2-simple P.V.'s of type I are already classified in [3], this completes the classification of all 2-simple P.V.'s. Here we say that (G, p, V) (or simply (G, p)) is a 2-simple P.V. if it is a prehomogeneous vector space of the following form: G = GL(1)k?s?t XG, X G2 where G1 and G2 are simple algebraic groups, p = the composition of the scalar multiplications GL (l)k+s + on each irreducible component and the representation p' = p1 ? p'1 + *** +Pk ? P'k+ (a1 + *** +s) ?1 + 1 ? (T1, + *** +T,) ofthegroupG1 x G2 where pi, aj (resp. p', Tj) are nontrivial irreducible representations of G1 (resp. G2). We write (G, p', V) instead of (G, p, V) for simplicity. To avoid confusion, we write + instead of (. Clearly each (GL(1) X G1 x G2, pi ? p) (i = 1,..., k) is an irreducible 2-simple P.V. If at least one of them is a nontrivial P.V. (see Definition 1.1), we call it a 2-simple P.V. of type I. On the other hand, if all of them are trivial P.V.'s, we call it a 2-simple P.V. of type II. In this case, we have G2= SL(n), Received by the editors March 3, 1986 and, in revised form, July 30, 1986. 1980 Mathematics Subject Classification (1985 Revision).
