Moduli for morphisms of abelian varieties

چکیده
We describe the moduli space of morphisms between polarized abelian varieties. The discrete invariants, derived from a Poincaré decomposition of morphisms, are the types of polarizations and of lattice homomorphisms occurring in the decomposition. They are sufficient in order to detect the irreducible components for the moduli space of morphisms which are compatible with the polarizations.

Siegel coordinates and moduli spaces for morphisms of Abelian varieties
We describe the moduli spaces of morphisms between polarized complex abelian varieties. The discrete invariants, derived from a Poincaré decomposition of morphisms, are the types of polarizations and of lattice homomorphisms occurring in the decomposition. For a given type of morphisms the moduli variety is irreducible, and is obtained from a product of Siegel spaces modulo the action of a disc...
متن کاملCYCLIC COVERING MORPHISMS ON M0,n
We study cyclic covering morphisms from M0,n to moduli spaces of unpointed stable curves of positive genus or compactified moduli spaces of principally polarized abelian varieties. Our main application is a construction of new semipositive vector bundles and nef divisors on M0,n, with a view toward the F-conjecture. In particular, we construct new extremal rays of Nef(M0,n/Sn). We also find an ...
متن کاملHilbert-Siegel moduli spaces in positive characteristic
Hilbert-Siegel varieties are moduli spaces for abelian varieties equipped with an action by an order OK in a fixed, totally real field K. As such, they include both the Siegel moduli spaces (use K = Q and the action is the standard one) and Hilbert-Blumenthal varieties (where the dimension of K is the same as that of the abelian varieties in question). In this paper we study certain phenomena a...
متن کاملThe Structure of the Moduli Spaces of Curves and Abelian Varieties
§ 1. The purpose of this talk is to collect together what seem to me to be the most basic moduli spaces (for curves and abelian varieties) and to indicate some of their most important interrelations and the key features of their internal structure, in particular those that come from the theta functions. We start with abelian varieties. Fix an integer g ^ 1. To classify g-dimensional abelian var...
متن کاملFourier-mukai Transforms for Abelian Varieties and Moduli of Stable Bundles
We classify Fourier-Mukai transforms for abelian varieties. In the case of a principally polarized abelian surface these are then used to identify a large family of moduli spaces of stable vector bundles as Hilbert schemes of points on the surface.
