Perverse-equivalence conjecture for quantum-cohomology eigenlines

Let AA be an alcove in the space of real stabilities, and let E(A)\mathcal{E}(A) be the set of joint eigenlines for quantum multiplication by equivariant cohomology classes of YY on HT(Y)H^\bullet_T(Y), with quantum parameter in AA. Perverse-equivalence conjecture. There is a natural indexing of E(A)\mathcal{E}(A) by the simple objects of the abelian category, or heart of the tt-structure, corresponding to AA, 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 tt-structures; no proof or resolution is supplied in the source.
