Boundedness conjecture for d-invariants on abelian Torelli subgroups
Boundedness conjecture for d-invariants on abelian Torelli subgroups
Let be a genus surface embedded in a homology sphere , and let be an abelian subgroup of the Torelli group. Boundedness conjecture. The set
is bounded. This conjecture predicts that the Heegaard Floer correction terms of the homology spheres obtained from 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.
