Abstract:
We will continue with the discussion about morphisms of schemes. We will see an explicit example of constructing morphisms of schemes by cutting up into affine open sets and then gluing them together. Then, we will define Z-valued points, where Z is a given scheme. This notion will lead us to determine a morphism not by its values at points but rather by its induced map of Z-valued points.
