Bochner-Kodaira-Nakano identity on K¨ahler manifolds We now proceed to explain the basic ideas of the Bochner technique used to prove vanishing theorems. Great simplifications occur in the computations if the hermitian metric on X is supposed to be K¨ahler, i.e. if the associatedfundamental (1,1)-form ω= iX ωjkdzj∧dzk. satisfies dω = 0. something good to invest in

WebIn fact, Theorem 1.5 is even a generalization of Theorem 1.1, where the latter corre-sponds to the special case that F is the trivial foliation of M by singletons. In the direction of Corollary 1.3, there is the following vanishing theorem for basic cohomology, which was discovered independently by Min-Oo, Ruh and Tondeur [Tond, Theorem WebBochner’s vanishing (reminder) THEOREM: (Bochner vanishing theorem) On a compact Ricci-at Calabi-Yau manifold, any holomorphic p-form is parallel with respect to the Levi-Civita connection: r( ) = 0. REMARK: Its proof is based on spinors: gives a harmonic spinor, and on a Ricci-at Riemannian spin manifold, any harmonic spinor is parallel.
