Normal subgroups of fundamental groups of affine curves in positive characteristic II
Amilcar Pacheco, Pavel Zalesskii, Katherine F. Stevenson
Let k be an algebraically closed field of characteristic p>0 and let C/k be a smooth connected affine curve. Denote by π1(C)

its algebraic fundamental group. The goal of this paper is to characterize a certain subset of closed normal subgroups
N
of
π1(C)
. In "Normal subgroups of fundamental groups of affine curves in positive characteristic" we proved the same result under the additional hypothesis that
k
had countable cardinality.
