有限域上Drinfeld半空间的自同构

Automorphisms of Drinfeld half-spaces over a finite field

Bertrand RÉMY, Amaury Thuillier, Annette Werner

摘要:

证明了有限域上Drinfeld半空间的自同构群是其基础向量空间的射影线性群。证明这一结果使用解析几何的意义上的布科维奇在有限域配备了平凡赋值。我们还考虑了基域的扩展。

英文摘要:

We show that the automorphism group of Drinfeld's half-space over a finite field is the projective linear group of the underlying vector space. The proof of this result uses analytic geometry in the sense of Berkovich over the finite field equipped with the trivial valuation. We also take into account extensions of the base field.
