Abstract
We show that every real division algebra, with a non-zero central idempotent, satisfying (x2, y2, x2) = 0 is flexible and isomorphic to either a commutative division algebra of dimension ≤ 2, a scalar isotope of a mutation of the quaternion algebra H or a kind of isotope of the octonion algebra O. 70 Bouchra Aharmim, Kandé Diaby, Oussama Fayz and Abdellatif Rochdi Mathematics Subject Classification: 17A35
期刊介绍:
The International Journal of Algebra and Computation publishes high quality original research papers in combinatorial, algorithmic and computational aspects of algebra (including combinatorial and geometric group theory and semigroup theory, algorithmic aspects of universal algebra, computational and algorithmic commutative algebra, probabilistic models related to algebraic structures, random algebraic structures), and gives a preference to papers in the areas of mathematics represented by the editorial board.
