Could you add the following, which presumably only uses that fibered products of affine schemes are affine (which is already known to mathlib)? @[priority 100]
instance affine_of_is_affine_of_is_affine {X Y : Scheme} [is_affine X] [is_affine Y]
(f : X ⟶ Y) : affine f := sorryOtherwise, it looks good to me. |
