Vanishing and injectivity theorems for Hodge modules
@article{Wu2015VanishingAI, title={Vanishing and injectivity theorems for Hodge modules}, author={Lei Wu}, journal={arXiv: Algebraic Geometry}, year={2015} }
We prove a surjectivity theorem for the Deligne canonical extension of a polarizable variation of Hodge structure with quasi-unipotent monodromy at infinity along the lines of Esnault-Viehweg. We deduce from it several injectivity theorems and vanishing theorems for pure Hodge modules. We also give an inductive proof of Kawamata-Viehweg vanishing for the lowest graded piece of the Hodge filtration of a pure Hodge module using mixed Hodge modules of nearby cycles.
