GradedLieAlgebras :: Number LieAlgebraMap

Number LieAlgebraMap -- multiplication of a number and a homomorphism

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 : M = lieAlgebra{a,b}

o1 = M

o1 : LieAlgebra
i2 : L = lieAlgebra{a,b}

o2 = L

o2 : LieAlgebra
i3 : f = map(L,M,{a,b})

o3 = f

o3 : LieAlgebraMap
i4 : describe(-2 f)

o4 = a =>  - 2 a
     b =>  - 2 b
     source => M
     target => L
