GradedLieAlgebras :: LieElement + LieElement

LieElement + LieElement -- addition of Lie elements

Synopsis

Description

The symbol + is used as infix notation for the Lie addition. The elements $x$ and $y$ must have 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
