Torsion orders of Fano hypersurfaces
Stefan Schreieder
We find new lower bounds on the torsion orders of very general Fano hypersurfaces over (uncountable) fields of arbitrary characteristic. Our results imply that unirational parametr…
Chern numbers of uniruled threefolds
Stefan Schreieder, Luca Tasin
In this paper we show that the Chern numbers of a smooth Mori fibre space in dimension three are bounded in terms of the underlying topological manifold. We also generalise a theor…
Holomorphic one-forms without zeros on threefolds
Feng Hao, Stefan Schreieder
We show that a smooth complex projective threefold admits a holomorphic one-form without zeros if and only if the underlying real 6-manifold fibres smoothly over the circle, and we…
Zeros of holomorphic one-forms and topology of Kähler manifolds
Stefan Schreieder
A conjecture of Kotschick predicts that a compact Kähler manifold fibres smoothly over the circle if and only if it admits a holomorphic one-form without zeros. In this paper w…
Variation of stable birational types in positive characteristic
Stefan Schreieder
Let k be an uncountable algebraically closed field and let Y be a smooth projective k-variety which does not admit a decomposition of the diagonal. We prove that Y is not stably bi…
The construction problem for Hodge numbers modulo an integer
Matthias Paulsen, Stefan Schreieder
For any positive integer m and any dimension n, we show that any n-dimensional Hodge diamond with values in Z/mZ is attained by the Hodge numbers of an n-dimensional smooth complex…
