An Integral Structure in Quantum Cohomology and Mirror Symmetry for Toric Orbifolds
نویسنده
چکیده
We introduce an integral structure in orbifold quantum cohomology associated to the K-group and the b Γ-class. In the case of compact toric orbifolds, we show that this integral structure matches with the natural integral structure for the Landau-Ginzburg model under mirror symmetry. By assuming the existence of an integral structure, we give a natural explanation for the specialization to a root of unity in Y. Ruan’s crepant resolution conjecture [63].

The quantum equivariant cohomology of toric manifolds through mirror symmetry
Using mirror symmetry as described by Hori and Vafa, we compute the quantum equivariant cohomology ring of toric manifolds. This ring arises naturally in topological gauged sigma-models and is related to the Hamiltonian Gromov-Witten invariants of the target manifold. e-mail address: [email protected] address: Valckenierstraat 65, 1018 XE Amsterdam, The Netherlands
متن کاملHomological mirror symmetry for toric orbifolds of toric del Pezzo surfaces
We propose a mathematical formulation of the algorithm of Hanany and Vegh [22] to associate quivers with relations to lattice polygons. We study the case of toric del Pezzo surfaces in detail and discuss its relation with coamoebas following Feng, He, Kennaway and Vafa [10]. As an application, we prove homological mirror symmetry for orbifolds of toric del Pezzo surfaces by finite subgroups of ...

In this paper we compute the integral cohomology groups for all examples of Calabi-Yau 3-folds obtained from hypersurfaces in 4-dimensional Gorenstein toric Fano varieties. Among 473 800 776 families of Calabi-Yau 3-folds X corresponding to 4-dimensional reflexive polytopes there exist exactly 32 families having non-trivial torsion in H∗(X, Z). We came to an interesting observation that the tor...
متن کاملWall-crossings in Toric Gromov–witten Theory Ii: Local Examples
In this paper we analyze six examples of birational transformations between toric orbifolds: three crepant resolutions, two crepant partial resolutions, and a flop. We study the effect of these transformations on genus-zero Gromov–Witten invariants, proving the Coates–Corti–Iritani–Tseng/Ruan form of the Crepant Resolution Conjecture in each case. Our results suggest that this form of the Crepa...
متن کامل2 00 5 Mirror Symmetry in Two Steps : a – I – B
We suggest an interpretation of mirror symmetry for toric varieties via an equivalence of two conformal field theories. The first theory is the twisted sigma model of a toric variety in the infinite volume limit (the A–model). The second theory is an intermediate model, which we call the I–model. The equivalence between the A–model and the I–model is achieved by realizing the former as a deform...
