Splitting families in Galois cohomology

Cyril Demarche, Mathieu Florence

Let $k$ be a field, with absolute Galois group $Γ$ . Let $A / k$ be a finite étale group scheme of multiplicative type, i.e. a discrete $Γ$ -module. Let $n \geq 2$ be an integer, and l…

Étale homotopy groups of algebraic groups and homogeneous spaces

Cyril Demarche, Tamás Szamuely

We show the vanishing of the second homotopy group of the étale homotopy type of a smooth connected algebraic group over a separably closed field, completed away from the character…
