WebThe Poitou-Tate duality is an analogue of the Poincaré duality. For instance, Tate reduced the conjecture of Birch and Swinnerton-Dyer over a global field of characteristic p to the … WebSerre duality, obtained by Jean–Pierre Serre in 1955 [8]. It relates sheaf cohomology groups on non-singular projective algebraic varieties. It is related via Hodge theory to the maybe more familiar Poincaré duality if the base ﬁeld is the complex numbers, but it considers the variety as a complex variety, not as a real manifold.
