proposition: Proposition poset_to_underlying_coprod_map_eq (fs : ∏ (j : J), ys j --> x) : CoproductArrow _ C (underlying_Coproduct E' ys (pr2 (EP ys))) fs = poset_to_underlying_coprod_map fs.
proof: Proof. use is_coprod_enriched_arrow_eq. - exact (pr2 (EP ys)). - intro j. refine (_ @ !(poset_to_underlying_coprod_map_pr fs j)). apply (CoproductInCommutes _ C _ (underlying_Coproduct E' ys (pr2 (EP ys))) _ fs). Qed.
