چکیده

Let (M,ω0) be a compact Kähler manifold of dimension n and D a divisor of M with at most normal crossing singularities . Let D = ∪i=1Di , where the Di are smooth divisors of M . Denote M \ D by M , called a quasi-compact Kähler manifold. j : M → M is the inclusion mapping. According to [3], one can construct a complete Kähler metric ω on M which is a Poincaré-like metric near the divisor and of finite volume. Let {M,HC = HZ ⊗ C,∇ = ∇1,0 + ∇0,1,F = {F}p=1,S} be a rational variation of polarized Hodge structures with weight m over M such that each F is a holomorphic subbundle of the local system HC and ∇1,0 satisfies the Griffiths’ infinitesimal period relation

Hodge Structures for Orbifold Cohomology

We construct a polarized Hodge structure on the primitive part of Chen and Ruan’s orbifold cohomology Hk orb(X) for projective SL-orbifolds X satisfying a “Hard Lefschetz Condition”. Furthermore, the total cohomology ⊕ p,q H p,q orb(X) forms a mixed Hodge structure that is polarized by every element of the Kähler cone of X. Using results of Cattani-Kaplan-Schmid this implies the existence of an...

Hodge structures on cohomology algebras and geometry

It is well-known (see eg [22]) that the topology of a compact Kähler manifold X is strongly restricted by Hodge theory. In fact, Hodge theory provides two sets of data on the cohomology of a compact Kähler manifold. The first data are the Hodge decompositions on the cohomology spaces H(X,C) (see (1.1) where V = H(X,Q)); they depend only on the complex structure. The second data, known as the Le...

Mixed Lefschetz Theorems and Hodge-Riemann Bilinear Relations

Statements analogous to the Hard Lefschetz Theorem (HLT) and the Hodge-Riemann bilinear relations (HRR) hold in a variety of contexts: they impose severe restrictions on the cohomology algebra of a smooth compact Kähler manifold or on the intersection cohomology of a projective toric variety; they restrict the local monodromy of a polarized variation of Hodge structure; they impose conditions o...

Asymptotic Hodge theory and quantum products

Assuming suitable convergence properties for the Gromov-Witten potential of a Calabi-Yau manifold X, one may construct a polarized variation of Hodge structure over the complexified Kähler cone of X. In this paper we show that, in the case of fourfolds, there is a correspondence between “quantum potentials” and polarized variations of Hodge structures that degenerate to a maximally unipotent bo...

The First L-Betti Number of Classifying Spaces for Variations of Hodge Structures

Classical Hodge theory gives a decomposition of the complex cohomology of a compact Kähler manifold M , which carries the standard Hodge structure {H(M), p + q = k} of weight k. Deformations of M then lead to variations of the Hodge structure. This is best understood when reformulating the Hodge decomposition in an abstract manner. Let HC = HR ⊕ C be a complex vector space with a real structure...
