1007.3730 (L. A. Wills-Toro)

Classification of some graded not necessarily associative division
algebras I

L. A. Wills-Toro
We study not necessarily associative (NNA) division algebras over the reals. We classify in this paper series those that admit a grading over a finite group $G$, and have a basis $\{v_g|g\in G\}$ as a real vector space, and the product of these basis elements respects the grading and includes a scalar structure constant with values only in $\{1,-1\}$. We classify here those graded by an abelian group $G$ of order $|G|\leq 8$ with $G$ non--isomorphic to $\z/8\z$. We will find the complex, quaternion, and octonion algebras, but also a remarkable set of novel non--associative division algebras.
