The Gamma Conjecture for local mirror symmetry
The Gamma Conjecture for local mirror symmetry
Let be the noncompact toric variety considered in the paper, with K-groups and paired by
Choose bases of and of satisfying . Let be the cohomology-valued hypergeometric series defined in the paper, let be the corresponding basis of , and let denote the mirror of under homological mirror symmetry. The Gamma Conjecture for local mirror symmetry. The expansion of satisfies
where is the holomorphic form on the mirror. Equivalently, for every mirror pair , the central charges match:
This is the local-mirror-symmetry form of the Gamma conjecture: the hypergeometric-series expression for the central charge on the coherent-sheaf side should agree with the oscillatory period on the mirror side. The supplied text does not state whether this conjecture has been resolved.
