LTP-strong conjecture for crepant Weierstrass fibrations
LTP-strong conjecture for crepant Weierstrass fibrations
Let be a smooth compact manifold, let be a Weierstrass fibration in
and let be a crepant resolution obtained by a sequence of blowups of in smooth centers, followed by taking the proper transform of . Write for the resulting blown-up ambient space, and let
be the inclusion. LTP-strong conjecture. The inclusion induces an isomorphism of rational Hodge structures
This is the stronger form of the numerical LTP-weak conjecture and is formulated after an example showing that an integral Hodge-structure isomorphism can fail because of torsion. Its status is not resolved in the supplied text.
