Definition disp_inv_invertible {B : bicat} {D : disp_bicat B} {x y : B} {f g : x --> y} {α : invertible_2cell f g} {xx : D x} {yy : D y} {ff : xx -->[ f ] yy} {gg : xx -->[ g ] yy} (αα : disp_invertible_2cell α ff gg) : disp_invertible_2cell (inv_of_invertible_2cell α) gg ff. Proof. use tpair. - exact (disp_inv_cell αα). - use tpair. + apply αα. + split ; cbn. * apply disp_vcomp_linv. * apply disp_vcomp_rinv. Defined.
