给定一个度为h的多项式,设Mh是具有Hilbert多项式h的正则极化复流形的模函子。文[23]中存在一个拟投射概型Mh和一个自然变换使得M是Mh的粗模概型。对于一个复的拟投射流形U,我们可以说一个态射<$U→ Mh通过模栈分解,或者说<$U是由一个族诱导的,如果<$U位于<$U(U)的像中,因此如果<$U =<$(<$:V→U)。
Given a polynomialhof degreenletMhbe the moduli functor of canonically polarized complex manifolds with Hilbert polynomialh. By [23] there exist a quasi-projective schemeMhtogether with a natural transformationsuch thatMhis a coarse moduli scheme forMh. For a complex quasi-projective manifoldUwe will say that a morphism ϕU→Mhfactors through the moduli stack, or that ϕ is induced by a family, if ϕ lies in the image of Ψ(U), hence if ϕ = Ψ(ƒ:V→U).
