Bochner vanishing theorem
Webwhich imply the vanishing of the Dolbeault cohomology groups on Hermitian manifolds. In Lemma 3.1 we give a slight modification of the Lichnerowicz type formula for the Dolbeault operator, proved by Bismut [2]. As an application we obtain the following theorem: Theorem 1.1 Let (M,g,J) be a compact 2n-dimensional (n >1) Hermitian manifold with

WebThe Bochner technique works for tensors that lie in the kernel of some Lich-nerowicz Laplacian LT = r⇤rT +cRic(T)=0. The idea is to use one of two maximum principles to show that T is parallel. In order to apply the maximum principle we need g(r⇤rT,T) 0 which by the equation for T is equivalent to showing g(Ric(T),T) 0. WebApr 1, 1988 · PDF On Apr 1, 1988, Pierre H.

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.
