Jordan algebra  

Definition

  • In abstract algebra, a Jordan algebra is a nonassociative algebra over a field whose multiplication satisfies the following axioms : 1. xy=yx (commutative law) 2. (xy)(xx)=x(y(xx)) (Jordan identity). The product of two elements x and y in a Jordan algebra is also denoted x ∘ y, particularly to avoid confusion with the product of a related associative algebra.
