设(G,V)是定义在数域k上的不可约预齐次向量空间,P ∈ k[V]是相对不变多项式,χ是G的有理特征标,使得.对于,设Gx是x的稳定子,并且是Gx的1的连通分量。我们定义L0为不具有非平凡有理特征的集合。然后我们通过以下积分定义(G,Y)的zeta函数,其中Φ是Schwartz-Bruhat函数,s是复变量,dg”是不变测度。
Let (G, V) be an irreducible prehomogeneous vector space defined over a number field k, P ∈ k[V] a relative invariant polynomial, and χ a rational character of G such that . For , let Gx be the stabilizer of x, and the connected component of 1 of Gx . We define L0 to be the set of such that does not have a non-trivial rational character. Then we define the zeta function for (G, Y) by the following integral where Φ is a Schwartz-Bruhat function, s is a complex variable, and dg” is an invariant measure.
