GradedLieAlgebras :: Number DerLie

Number DerLie -- Multiplication of a Number and a Derivation

Synopsis

Description

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.

i1 : L = lieAlgebra{a,b}

o1 = L

o1 : LieAlgebra
i2 : d = derLie{a a b,b b a}

o2 = d

o2 : DerLie
i3 : peekLie(-2 d)

o3 = a => 2 (a b a)
     b =>  - 2 (b b a)
     maplie => id
     sign => 0
     weight => {2, 0}
     sourceLie => L
     targetLie => L
