On the Cohomological Crepant Resolution Conjecture for Weighted Projective Spaces
نویسنده
چکیده
We investigate the Cohomological Crepant Resolution Conjecture for reduced Gorenstein weighted projective spaces. Using toric methods, we prove this conjecture in some new cases. As an intermediate step, we show that weighted projective spaces are toric Deligne-Mumford stacks. We also describe a combinatorial model for the orbifold cohomology of weighted projective spaces.

Wall-crossings in Toric Gromov–witten Theory I: Crepant Examples
The Crepant Resolution Conjecture of Ruan and Bryan–Graber asserts that certain generating functions for genus-zero Gromov–Witten invariants of an orbifold X can be obtained from their counterparts for a crepant resolution of X by analytic continuation followed by specialization of parameters. In this paper we use mirror symmetry to determine the relationship between the genus-zero Gromov–Witte...
متن کاملOn the Crepant Resolution Conjecture in the Local Case
In this paper we analyze four examples of birational transformations between local Calabi– Yau 3-folds: two crepant resolutions, a crepant partial resolution, 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 th...

We compare the Chen-Ruan cohomology ring of the weighted projective spaces P(1, 3, 4, 4) and P(1, ..., 1, n) with the cohomology ring of their crepant resolutions. In both cases, we prove that the Chen-Ruan cohomology ring is isomorphic to the quantum corrected cohomology ring of the crepant resolution after suitable evaluation of the quantum parameters. For this, we prove a formula for the Gro...

متن کاملAn Example of Crepant Resolution Conjecture in Two Steps
We study the relation among the genus 0 Gromov-Witten theories of the three spaces X ← Z ← Y , where X = [C/Z3], Z is obtained by a weighted blowup at the stacky point of X , and Y is the crepant resolution of the A2 singularity. We formulate and verify a statement similar to the Crepant Resolution Conjecture of Bryan and Graber.
