Perverse-equivalence conjecture for quantum-cohomology eigenlines
Perverse-equivalence conjecture for quantum-cohomology eigenlines
Let be an alcove in the space of real stabilities, and let be the set of joint eigenlines for quantum multiplication by equivariant cohomology classes of on , with quantum parameter in . Perverse-equivalence conjecture. There is a natural indexing of by the simple objects of the abelian category, or heart of the -structure, corresponding to , such that monodromy along paths crossing the boundary divisor transversely is given by the permutations of simple objects determined by the corresponding perverse equivalence. This conjecturally identifies quantum-cohomology monodromy with the wall-crossing behavior of hearts of -structures; no proof or resolution is supplied in the source.
