Dual of the empty function Thanks for the correct notion of duality in this case; I know just enough category theory (picked up through functional programming) to ask foolish questions like these, but not nearly enough yet to yield any valuable insight. |

Dual of the empty function Thanks for the clarification. In hindsight this was quite a silly question; I essentially ignored the contradiction that arose from the $\exists$ part of $\forall x \in X, \exists y \in Y$ s.t. $(x,y) \in f$ |

Do there exist interesting binary relations satisfying reflexivity and symmetry, but not transitivity? Thanks! This was the clarification I was more or less looking for; I'd initially thought that the relation might represent those directed graphs with an identity edge at each vertex and two (opposing) edges between each vertex where the relation holds; your representation is much cleaner. |
