Hurwitz代数的同位素

Isotopes of Hurwitz algebras

Erik Darpö

摘要:

我们研究的类的所有代数是同位素的一个Hurwitz代数。这类代数的同构类对应于某个群作用的轨道。一个完整的,几何直观的描述类的同位素汉密尔顿的四元数。作为一个应用,我们证明了如何从我们的一般结果中推导出关于有限维复合代数分类的一些结果。

英文摘要:

We study the class of all algebras that are isotopic to a Hurwitz algebra. Isomorphism classes of such algebras are shown to correspond to orbits of a certain group action. A complete, geometrically intuitive description of the category of isotopes of Hamilton's quaternions is given. As an application, we demonstrate how some results concerning the classification of finite-dimensional composition algebras can be deduced from our general results.
