P=W for Lagrangian fibrations and degenerations of hyper-Kähler manifolds

Andrew Harder, Zhiyuan Li, Junliang Shen +1

We identify the perverse filtration of a Lagrangian fibration with the monodromy weight filtration of a maximally unipotent degeneration of compact hyper-Kähler manifolds.

Torus fibers and the weight filtration

Andrew Harder

We show that if $(X, Y)$ is a simple normal crossings log Calabi--Yau pair, then there is a real torus of dimension equal to the codimension of the smallest stratum of $Y$ which can…
