Extended Picard complexes and linear algebraic groups

Mikhail Borovoi, Joost van Hamel

For a smooth geometrically integral variety $X$ over a field $k$ of characteristic 0, we introduce and investigate the extended Picard complex $U P i c (X)$ . It is a certain complex of…

Algebraic cycles and topology of real Enriques surfaces

Frédéric Mangolte, Joost van Hamel

For a real Enriques surface Y we prove that every homology class in H_1(Y(R), Z/2) can be represented by a real algebraic curve if and only if all connected components of Y(R) are…
