1. Composition algebraIn mathematics, a composition algebra A over a field K is a unital (but not necessarily associative) algebra over K together with a nondegenerate quadratic form N which satisfies for all x and y in A.   The quadratic form N is often referred to as a norm on A.   Composition algebras are also called normed algebras (not to be confused with normed algebras in the sense of functional analysis).
