In this section we show that the fundamental group of a connected proper scheme over a henselian local ring is the same as the fundamental group of its special fibre. We also prove a variant of this result for a henselian pair.

Visit Stack Exchange WebApr 7, 2024 · A henselian field (K, v) is called a tame field if its algebraic closure K ˜ with the unique extension of the valuation is a tame extension. The Lemma of Ostrowski (see [6], [12]) shows that every henselian valued field of residue characteristic 0 is a tame field. For the formulation of our main theorems we will need some more definitions.
