Query: On representations of isometric isomorphisms between some monoid of
  functions   We prove that each isometric isomorphism, between the monoids of all
nonegative 1-Lipschitz maps defined on invariant metric groups and equiped with
the inf-convolution law, is given canonically from an isometric isomorphism
between their groups of units.
