Triality与Etale代数

Triality and etale algebras

Max-Albert Knus, Jean-Pierre Tignol

摘要:

Trialitarian自同构与D4型Dynkin图的3阶自同构有关。利用值在D4型外尔群中的Galois上同调,对含有四次子代数的具有平凡判别式的八次代数进行了分类.本文讨论了这种扩展的尝试性。

英文摘要:

Trialitarian automorphisms are related to automorphisms of order 3 of the Dynkin diagram of type D4. Octic etale algebras with trivial discriminant, containing quartic subalgebras, are classified by Galois cohomology with value in the Weyl group of type D4. This paper discusses triality for such &#233tale extensions.
