Calabi-Yau Three-folds and Moduli of Abelian Surfaces II
نویسندگان
چکیده
The main goal of this paper, which is a continuation of [GP1], [GP2] and [GP3], is to describe birational models for moduli spaces Ad of polarized abelian surfaces of type (1, d) for small values of d, and for moduli spaces of such polarized abelian surfaces with suitably defined partial or canonical level structure. We can then decide the uniruledness, unirationality or rationality of nonsingular models of compactifications of these moduli spaces (which are quasi-projective 3-folds, possibly singular). Since these properties are birational invariants, this determines the corresponding properties of those moduli spaces.

On the Incompleteness of the Weil-petersson Metric along Degenerations of Calabi-yau Manifolds
The classical Weil-Petersson metric on the Teichmüller space of compact Riemann surfaces is a Kähler metric, which is complete only in the case of elliptic curves [Wo]. It has a natural generalization to the deformation spaces of higher dimansional polarized Kähler-Einstein manifolds. It is still Kähler, and in the case of abelian varieties and K3 surfaces, the Weil-Petersson metric turns out t...
متن کاملSome Features of ( 0 , 2 ) Moduli Space
We discuss some aspects of perturbative (0, 2) Calabi-Yau moduli space. In particular, we show how models with different (0, 2) data can meet along various sub-loci in their moduli space. In the simplest examples, the models differ by the choice of desingularization of a holomorphic V-bundle over the same resolved Calabi-Yau base while in more complicated examples, even the smooth Calabi-Yau ba...

We briefly review the formal picture in which a Calabi-Yau n-fold is the complex analogue of an oriented real n-manifold, and a Fano with a fixed smooth anticanonical divisor is the analogue of a manifold with boundary, motivating a holomorphic Casson invariant counting bundles on a Calabi-Yau 3-fold. We develop the deformation theory necessary to obtain the virtual moduli cycles of [LT], [BF] ...

Calabi–Yau m-folds (M,J, ω,Ω) are compact complex manifolds (M,J) of complex dimension m, equipped with a Ricci-flat Kähler metric g with Kähler form ω, and a holomorphic (m, 0)-form Ω of constant length |Ω| = 2. Using Algebraic Geometry and Yau’s solution of the Calabi Conjecture, one can construct them in huge numbers. String Theorists (a species of theoretical physicist) are very interested ...
