GradedLieAlgebras :: LieElement - LieElement

LieElement - LieElement -- subtraction of Lie elements

Synopsis

Description

The symbol - is used as infix notation for the Lie subtraction. The elements $x$ and $y$ must hade the same weight and sign.

i1 : L = lieAlgebra{a,b}

o1 = L

o1 : LieAlgebra
i2 : b b b a - a a a b

o2 = (a a b a) + (b b b a)

o2 : L
