The symbol SPACE is used as notation for multiplication by scalars. The scalars are of type Number if the field is QQ, otherwise the scalars are of type RingElement. If the Lie element is surrounded by parentheses, the SPACE may be omitted.
i1 : L = lieAlgebra{a,b} o1 = L o1 : LieAlgebra |
i2 : - 3(b b a + 2 a a b) o2 = 6 (a b a) - 3 (b b a) o2 : L |
