Extension of torsors and prime to $p$ fundamental group scheme

Marco Antei, Jimmy Calvo-Monge

Let $R$ be a discrete valuation ring with fraction field $K$ . Let $X$ be a proper and faithfully flat $R$ -scheme, endowed with a section $x \in X (R)$ , with connected and reduced ge…

On the fundamental group scheme of rationally chain connected varieties

Marco Antei, Indranil Biswas

Let $k$ be an algebraically closed field. Chambert-Loir proved that the étale fundamental group of a normal rationally chain connected variety over $k$ is finite. We prove that the…

Pushout of quasi-finite and flat group schemes over a Dedekind ring

Marco Antei

Let $G$ , $G_{1}$ and $G_{2}$ be quasi-finite and flat group schemes over a complete discrete valuation ring $R$ , $φ_{1} : G \to G_{1}$ any morphism of $R$ -group schemes and $φ_{2} : G \to G_{2}$ a m…
