AlgebraicGeometry.LocallyRingedSpace.residueFieldMap

{X Y : AlgebraicGeometry.LocallyRingedSpace} →
  (f : X ⟶ Y) → (x : ↑X.toTopCat) → Y.residueField ((CategoryTheory.ConcreteCategory.hom f.base) x) ⟶ X.residueField x

If X ⟶ Y is a morphism of locally ringed spaces and x a point of X, we obtain a morphism of residue fields in the other direction.
