A morphism of pointed sets[1][2] is equivalently:

  • A morphism of $\mathbb {E}_{0}$-monoids in $\webleft (\mathrm{N}_{\bullet }\webleft (\mathsf{Sets}\webright ),\text{pt}\webright )$.
  • A morphism of pointed objects in $\webleft (\mathsf{Sets},\text{pt}\webright )$.


Footnotes

[1] Further Terminology: Also called a pointed function.
[2] Further Terminology: In the context of monoids with zero as models for $\mathbb {F}_{1}$-algebras, morphisms of pointed sets are also called morphism of $\mathbb {F}_{1}$-modules.
