proposition: Lemma LNWFS_inv_in_precat_if_Ff_inv_in_precat {L L' : total_category (LNWFS C)} (τ : L --> L') (τ' : L' --> L) (HFf : is_inverse_in_precat (pr1 τ) (pr1 τ')) : is_inverse_in_precat τ τ'.
proof: Proof. split; (apply subtypePath; [intro; apply isaprop_lnwfs_mor_axioms|]). - exact (pr1 HFf). - exact (pr2 HFf). Qed.
