WebI'm trying to solve Exercise 5.1 of Chapter II of Hartshorne - Algebraic Geometry. I'm fine with the first 3 parts, but I'm having troubles with the very last part, which asks to prove the projection formula: Let f: X → Y be a morphism of ringed spaces, F an O X -module and E a locally free O Y -module of finite rank. Web2. On page 70 Hartshorne constructs the structure sheaf on the spectrum of a commutative ring. The sections on an open subset are functions valued in the localizations which are given locally by fractions. Now one has to find a ring structure on this set. But this is easy using the ring structure of the localizations. WebBy modules is an OX -module Solution: Assume morphism of OX -modules, OX de nition, the ker (ϕ) is a subsheaf of P. Also, the kernel of a by de nition. Using 1.6, 1.7, and the de nitions of a quotient of we see that ϕ 0 → ker (ϕ) → P → OX → 0 is exact. black wood tiles
