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). WebLet Rbe a graded ring. We say that an R-module M is graded if there is a direct sum decomposition M= M n2N M n; compatible with the grading on Rin the obvious way, R dM n ˆM d+n: A morphism of graded modules is an R-module map ˚: M! N of graded modules, which respects the grading, ˚(M n) ˆN n: A graded submodule is a submodule for which …
