单缀Chevalley群的非结合Frobenius代数

Non-associative Frobenius algebras for simply laced Chevalley groups

Tom De Medts, Michiel Van Couwenberghe

摘要:

我们提供了一个明确的建设一类交换,非结合代数的每一个简单的Chevalley群的简单花边型。此外,我们还赋予这些代数一个相伴的双线性型,使它们成为Frobenius代数。这个类包括一个3876维的代数,其上的Chevalley群的E8型行为的自同构。我们还证明了这些代数允许(轴)分解代数的结构。

英文摘要:

We provide an explicit construction for a class of commutative, non-associative algebras for each of the simple Chevalley groups of simply laced type. Moreover, we equip these algebras with an associating bilinear form, which turns them into Frobenius algebras. This class includes a 3876-dimensional algebra on which the Chevalley group of type E8 acts by automorphisms. We also prove that these algebras admit the structure of (axial) decomposition algebras.
