Abelianization of the F-divided fundamental group scheme

Abstract

Let $(X,x_0)$ be a pointed smooth proper variety defined over an algebraically closed field. The Albanese morphism for $(X,x_0)$ produces a homomorphism from the abelianization of the $F$-divided fundamental group scheme of $X$ to the $F$-divided fundamental group of the Albanese variety of $X$. We prove that this homomorphism is surjective with finite kernel. The kernel is also described.
