Tangent lifting of deformations in mixed characteristic
Torsten Ekedahl, Nick I. Shepherd-Barron
This article presents a new approach to the unobstructedness result for deformations of Calabi-Yau varieties by introducing the tangent lifting property for a functor on artinian l…

On non-liftable Calabi-Yau threefolds
Torsten Ekedahl
Only two ways to construct non-liftable Calabi-Yau threefolds are currently known, one example by Hirokado and one method of Schröer. This article computes some cohomological invar…

The order of the top Chern class of the Hodge bundle on the moduli space of abelian varieties
Torsten Ekedahl, Gerard van der Geer
We give upper and lower bounds for the order of the top Chern class of the Hodge bundle on the moduli space of principally polarized abelian varieties.
