Proposition local_equivalence_inv_twocell_psfunctor {x y : B₁} {f g : x --> y} (τ : f ==> g) : local_equivalence_inv_twocell (##F τ) = (local_equivalence_unit_inv2cell f)^-1 • τ • local_equivalence_unit_inv2cell g. Proof. rewrite !vassocl. use vcomp_move_L_pM. { is_iso. } cbn. refine (!_). apply local_equivalence_unit_natural. Qed.
