GradedLieAlgebras :: - LieAlgebraMap

- LieAlgebraMap -- unary negation

Synopsis

Description

The symbol - is used as notation for the negation of Lie homomorphisms.

i1 : M = lieAlgebra{a,b}

o1 = M

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

o2 = L

o2 : LieAlgebra
i3 : f = map(L,M)

o3 = f

o3 : LieAlgebraMap
i4 : describe(-f)

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