Connected algebraic groups acting on three-dimensional Mori fibrations

Jérémy Blanc, Andrea Fanelli, Ronan Terpereau

We study the connected algebraic groups acting on Mori fibrations $X \to Y$ with $X$ a rational threefold and $dim (Y) \geq 1$ . More precisely, for these fibre spaces we co…

The Fontaine-Ogus realisation of Laumon 1-motives

Nicola Mazzari

We construct the (filtered) Ogus realisation of Laumon 1-motives over a number field. This realisation extends the functor defined on Deligne 1-motives by Andreatta, Barbieri-Viale…

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…

Rational curves on $V_{5}$ and rational simple connectedness

Andrea Fanelli, Laurent Gruson, Nicolas Perrin

In this paper the notion of rational simple connectedness for the quintic Fano threefold $V_{5} \subset P^{6}$ is studied and unirationality of the moduli spaces $\overline{M}_…
