Boundedness conjecture for d-invariants on abelian Torelli subgroups

From papers

Let SS be a genus gg surface embedded in a homology sphere YY, and let HH be an abelian subgroup of the Torelli group. Boundedness conjecture. The set

{d(Yϕ)ϕH}\{d(Y_\phi) \mid \phi \in H\}

is bounded. This conjecture predicts that the Heegaard Floer correction terms of the homology spheres obtained from YY by the mapping classes in an abelian Torelli subgroup remain uniformly bounded, strengthening the preceding boundedness result for abelian groups generated by separating twists and bounding pair maps.
