The equality of Landau–Ginzburg Hodge invariants

Let (Y,w)(Y,w) be a Landau–Ginzburg model admitting a tame compactification. Let fp,q(Y,w)f^{p,q}(Y,w) be the Hodge-theoretic invariants defined from the Hodge filtration on relative cohomology, and let hp,q(Y,w)h^{p,q}(Y,w) be those defined from the monodromy filtration. A Landau–Ginzburg Hodge invariants conjecture asserts that

hp,q(Y,w)=fp,q(Y,w).h^{p,q}(Y,w)=f^{p,q}(Y,w).

This is the equality predicted by the Katzarkov–Kontsevich–Pantev framework; in the source it is subsequently known under additional hypotheses, but no unconditional resolution is supplied here.
