为了陈述标题中提到的猜想,我们需要回忆一些关于Shimura簇的术语和结果;作为这些的一般参考,我们使用[20,第1-2节]。设S:= Resc/Grnc为R上的代数群,通过限制乘法群的从C到R的标量而得到。对于1[8]-向量空间V,则等价于给出R-Hodge结构或S在其上的作用. Shimura基准是Q上的一个具有Ga连通的约化仿射代数群的对(GX),且XaG(R)-共轭类在代数群Hom(S,GR.)的态射集中,满足[20,定义1.4]的三个条件(即,[13]的通常条件(2.1.1-3))。这些条件意味着X具有自然的复杂结构(实际上,连通分支是埃尔米特对称域),使得G在Q-向量空间上的每一个表示定义了X上Hodge结构的一个可极化变化。对于(G X)是Shimura基准,且G(Af)的Ka紧开子群,我们设ShK(G,X)((C)表示复解析变量G(Q)\(X × G(Af)/ K),它具有拟投射复代数簇的自然结构,记为Sill G2,它将X1映射到X2;对Gi(Af)和G2(Ao)的K1和K2紧开子群,其中f(Ko)包含在K2中,得到了ShK,(G1,X1)c到ShK 2(G2,X2)c的态射Sh(f)。
In order to state the conjecture mentioned in the title, we need to recall some terminology and results on Shimura varieties; as a general reference for these, we use [20, Sections 1–2]. So let S:= Resc/Grnc be the algebraic group over R obtained by restriction of scalars from C to R of the multiplicative group. For V an 1[8-vector space, it is then equivalent to give an R-Hodge structure or an action by S on it. A Shimura datum is a pair(G X)withGa connected reductive affine algebraic group over Q, andXa G(R)-conjugacy class in the set of morphisms of algebraic groups Hom(S, GR.), satisfying the three conditions of [20, Def. 1.4] (i.e., the usual conditions (2.1.1-3) of [13]). These conditions imply thatXhas a natural complex structure (in fact, the connected components are hermitian symmetric domains), such that every representation ofGon a Q-vector space defines a polarizable variation of Hodge structure onX.For(G X)a Shimura datum, andKa compact open subgroup of G(Af), we let ShK(G, X)((C) denote the complex analytic varietyG(Q)\(X x G(A f )/ K)which has a natural structure of quasi-projective complex algebraic variety, denoted Sill G2 that maps X1to X2; for K1and K2 compact open subgroups of Gi(Af) and G2 (AO withf (KOcontained in K2, such anfinduces a morphism Sh(f)from ShK, (G1, Xi)c to ShK2(G2, X2)c.
