proposition: Proposition span_sqr_eq {a₁ a₂ b₁ b₂ : C} {f : a₁ --> a₂} {g : b₁ --> b₂} {s₁ : span a₁ b₁} {s₂ : span a₂ b₂} (sq₁ sq₂ : span_sqr f g s₁ s₂) (p : span_sqr_ob_mor sq₁ = span_sqr_ob_mor sq₂) : sq₁ = sq₂.
proof: Proof. use subtypePath. { intro. apply isapropdirprod ; apply homset_property. } exact p. Qed.
