AssociatedJordanAlgebra(R, A)

lie.spad line 53 [edit on github]

• R: CommutativeRing

• A: NonAssociativeAlgebra R

AssociatedJordanAlgebra takes an algebra A and uses *$A to define the new multiplications a*b := (a *\$A b + b *\$A a)/2 (anticommutator). The usual notation {a, b}_+ cannot be used due to restrictions in the current language. This domain only gives a Jordan algebra if the Jordan-identity (a*b)*c + (b*c)*a + (c*a)*b = 0 holds for all a, b, c in A. This relation can be checked by jordanAdmissible?()$A. If the underlying algebra is of type FramedNonAssociativeAlgebra(R) (i.e. a non associative algebra over R which is a free R-module of finite rank, together with a fixed R-module basis), then the same is true for the associated Jordan algebra. Moreover, if the underlying algebra is of type FiniteRankNonAssociativeAlgebra(R) (i.e. a non associative algebra over R which is a free R-module of finite rank), then the same true for the associated Jordan algebra.
