A conjecture about funcoids proved

WARNING: The proof was with an error!

I have proved the following theorem:

Theorem \forall H \in \mathrm{up} (g \circ f) \exists F \in \mathrm{up}\, f, G \in \mathrm{up}\, g : H \sqsupseteq G \circ F for every composable funcoids f and g.

This theorem (being a conjecture at that time) was used in my alternative proof of Urysohn’s lemma. Now the proof is complete.

See my site for details.
