The real cycle class map
Jens Hornbostel, Matthias Wendt, Heng Xie +1
The classical cycle class map for a smooth complex variety sends cycles in the Chow ring to cycles in the singular cohomology ring. We study two cycle class maps for smooth real va…

The torsion in the cohomology of wild elliptic fibers
Leif Zimmermann
Given an elliptic fibration over the spectrum of a complete discrete valuation ring with algebraically closed residue field, we use a Hochschild--Serre spectral…

The maximal unipotent finite quotient, unusual torsion in Fano threefolds, and exceptional Enriques surfaces
Andrea Fanelli, Stefan Schröer
We introduce and study the maximal unipotent finite quotient for algebraic group schemes in positive characteristics. Applied to Picard schemes, this quotient encodes unusual torsi…
