Higher-genus quasimap wall-crossing conjecture for Fano index at least two

Let (W,G,θ)(W,{\bf G},\theta) be a Fano triple of Fano index at least 22, and let σ1ψ1a1,,σkψkakg,k,βε\langle\sigma_1\psi_1^{a_1},\ldots,\sigma_k\psi_k^{a_k}\rangle^\varepsilon_{g,k,\beta} denote its descendant quasimap invariants at stability parameter ε\varepsilon. Higher-genus Fano wall-crossing conjecture. The descendant quasimap invariants

σ1ψ1a1,,σkψkakg,k,βε\langle\sigma_1\psi_1^{a_1},\ldots,\sigma_k\psi_k^{a_k}\rangle^\varepsilon_{g,k,\beta}

are independent of ε\varepsilon. This is a proposed higher-genus extension of the genus-zero wall-crossing theory. The paper states it as a direction for future work, so no general resolution is supplied.
