zeroMap -- make the zero map

Synopsis

• Usage:

  f=zeroMap(M,L)

• Inputs:
  • M, an instance of the type LieAlgebra,
  • L, an instance of the type LieAlgebra,
• Outputs:
  • f, an instance of the type LieAlgebraMap,

Description

i1 : L = lieAlgebra{a,b}

o1 = L

o1 : LieAlgebra

i2 : M = lieAlgebra{a,b}

o2 = M

o2 : LieAlgebra

i3 : f=zeroMap(M,L)

o3 = 0

o3 : LieAlgebraMap

i4 : describe f

o4 = a => 0
     b => 0
     source => L
     target => M
