Bogomolov–Sommese vanishing theorem

Not to be confused with Le Potier's vanishing theorem.

In algebraic geometry, the Bogomolov–Sommese vanishing theorem is a result related to the Kodaira–Itaka dimension. It is named after Fedor Bogomolov and Andrew Sommese. Its statement has differing versions:

Bogomolov–Sommese vanishing theorem for snc pair: Let X be a projective manifold (smooth projective variety), D a simple normal crossing divisor (snc divisor) and $A\subseteq \Omega _{X}^{p}(\log D)$ an invertible subsheaf. Then the Kodaira–Itaka dimension $\kappa (A)$ is not greater than p.

This result is equivalent to the statement that:

$H^{0}\left(X,A^{-1}\otimes \Omega _{X}^{p}(\log D)\right)=0$

for every complex projective snc pair $(X,D)$ and every invertible sheaf $A\in \mathrm {Pic} (X)$ with $\kappa (A)>p$.

Therefore, this theorem is called the vanishing theorem.

Bogomolov–Sommese vanishing theorem for lc pair: Let (X,D) be a log canonical pair, where X is projective. If $A\subseteq \Omega _{X}^{[p]}(\log \lfloor D\rfloor )$ is a $\mathbb {Q}$-Cartier reflexive subsheaf of rank one, then $\kappa (A)\leq p$.
