I have seen many books and articles about this, and they all treat it as an exercise to the reader. I am willing to admit that I may be too stupid for the exercise, but is there a textbook or survey article that explains this in détail? I mean it is somehow ...

WebThe Grassmannian As A Scheme. In the realm of algebraic geometry, the Grassmannian can be constructed as a scheme by expressing it as a representable functor. Let be a quasi-coherent sheaf on a scheme S. Fix a positive integer r.
