WebSep 22, 2024 · 1 Answer. Every abelian sheaf F on X whose support is contained in Z, has vanishing cohomology groups H i ( X, F) for i > dim Z. Proof. The support of an abelian sheaf is the set of points where the stalk is nonzero. If the support of F is contained in Z, then F is equal to i ∗ ( i − 1 F) where i: Z → X is the inclusion map (look at stalks). fastweld 10 50mlWebWikiZero Özgür Ansiklopedi - Wikipedia Okumanın En Kolay Yolu fast weight loss treadmill workout
