map(CpMackeyFunctor,CpMackeyFunctor,ZZ) -- constructs the zero map between two Mackey functors, or a multiple of the identity map

• Function: map

• Usage:

  map(N,M,0)

  map(M,M,n)

• Inputs:
  • N, a C_p Mackey Functor, target
  • M, a C_p Mackey Functor, source
  • n, an integer,
• Optional inputs:
  • Degree => ..., default value null, constructs a map between two Mackey functors
  • DegreeLift => ..., default value null, constructs a map between two Mackey functors
  • DegreeMap => ..., default value null, constructs a map between two Mackey functors
• Outputs:
  • a Mackey Functor homomorphism, the map $n*\mathrm{id}$ from M to N, if such a thing exists.
