Adapted Differentials on Campana Orbifolds
Pedro Núñez (University of Freiburg)
Abstract
Adapted differentials play an important role in Campana's birational classification program. In this talk we will discuss two results concerning them. These differential forms are usually only defined over suitably ramified covers, and the first result shows that they can be seen as a qfh-sheaf on the whole category of schemes over the orbifold. The second result ensures that we can extend (reflexive) adapted differential 1-forms on such a suitably ramified cover to a resolution of singularities of the cover, provided that the orbifold is klt. As an application, we construct the Albanese of a Campana orbifold with quotient singularities.
