Graded ring math

WebLet S be a graded ring. The locally ringed space \text {Proj} (S) is a scheme. The standard opens D_ {+} (f) are affine opens. For any graded S -module M the sheaf \widetilde M is a quasi-coherent sheaf of \mathcal {O}_ {\text {Proj} (S)} -modules. Proof. Consider a standard open D_ {+} (f) \subset \text {Proj} (S).
