Vanishing and a counterexample for Witt divisorial sheaves
Niklas Lemcke
First we refine the duality theory for Witt divisorial sheaves on smooth projective varieties over a perfect field of positive characteristic. Building on previous work [Lem22], we…

Duality for Witt-divisorial sheaves
Niklas Lemcke
We adapt ideas from Ekedahl [Eke84] to prove a Serre-type duality for Witt-divisorial sheaves of -Cartier divisors on a smooth projective variety over a perfect field of…
