Joyce's special Lagrangian invariant conjecture for Calabi–Yau 3-folds

From papers

Let (M,J,ω,Ω)(M,J,\omega,\Omega) be an (almost) Calabi–Yau 33-fold with compact underlying 66-manifold MM, complex structure JJ, Kähler form ω\omega, and holomorphic volume form Ω\Omega. Let Db(F(M,ω))D^b(F(M,\omega)) denote the derived Fukaya category, and let τ\tau be the Bridgeland-type stability condition determined by Ω\Omega. Joyce's special Lagrangian invariant conjecture. There should exist invariants Kα(J)QK^\alpha(J)\in\mathbb Q for αH3(M,Z)\alpha\in H_3(M,\mathbb Z) counting special Lagrangian homology 33-spheres NMN\subset M with [N]=α[N]=\alpha, as well as possibly other immersed or singular special Lagrangian 33-folds. They should be independent of ω\omega and of complex rescalings of Ω\Omega, transform according to the triangulated-category extension of the stated wall-crossing formula under deformation of JJ, and agree under mirror symmetry with the corresponding invariants of τ~\tilde\tau-semistable objects in Db(coh(P))D^b(\operatorname{coh}(P)) for a mirror Calabi–Yau 33-fold PP. The source further proposes analogous systems counting configurations and a possible extension to (almost) Calabi–Yau mm-folds for m2m\geq 2. This is presented as an extension of the extended Donaldson–Thomas conjecture and is not resolved in the source.
