The manifold algebraic g-conjecture

Let Δ\Delta be a homology manifold, and let Lsi(Δ)L^i_s(\Delta) denote the set of pairs consisting of a linear system of parameters and a one-form satisfying the partial Lefschetz condition in degree ii as defined in the source. Manifold algebraic g-conjecture. For every id/2i\ge\lceil d/2\rceil,

Lsi(Δ).L^i_s(\Delta)\ne\emptyset.

This is proposed as an extension of the algebraic g-conjecture from homology spheres to homology manifolds, with or without boundary. Its status is open.
