Nakano's vanishing theorem

In mathematics, specifically in the study of vector bundles over complex Kähler manifolds, the Nakano vanishing theorem, sometimes called the Akizuki–Nakano vanishing theorem, generalizes the Kodaira vanishing theorem.^[1][2][3] Given a compact complex manifold M with a holomorphic line bundle F over M, the Nakano vanishing theorem provides a condition on when the cohomology groups H q ( M ; Ω p ( F ) ) {\textstyle H^{q}(M;\Omega ^{p}(F))} equal zero. Here, Ω p ( F ) {\textstyle \Omega ^{p}(F)} denotes the sheaf of holomorphic (p,0)-forms taking values on F. The theorem states that, if the first Chern class of F is negative, H q ( M ; Ω p ( F ) ) = 0  when  q + p < n . {\displaystyle H^{q}(M;\Omega ^{p}(F))=0{\text{ when }}q+p<n.} Alternatively, if the first Chern class of F is positive, H q ( M ; Ω p ( F ) ) = 0  when  q + p > n . {\displaystyle H^{q}(M;\Omega ^{p}(F))=0{\text{ when }}q+p>n.}
