Definition

< 2-poset of partial maps

Given a dagger 2-poset AA, the 2-poset of partial maps Map (A)Map_\bot(A) is the sub-2-poset whose objects are the objects of AA and whose morphisms are the partial maps of AA.

Examples

  • For the dagger 2-poset of sets and relations RelRel, the 2-poset of partial maps Map (Rel)Map_\bot(Rel) is equivalent to the category of sets and partial functions Set Set_\bot.
