Let $X$ be a smooth compact complex manifold of dimension $n$. Suppose $L$ is a line bundle on $X$ such that $dim(H^0(X,L^k))>c\cdot k^n$ for $c>0$ and $k>>0$.

Question. Is it true that $X$ is Moishezon? Is there some reference for this statement?

    $\begingroup$ The question correspond to volume of line bundle. $L$ is big, implies the projectivity of X is Moishezon. Note that $L$ is big iff $Vol(L)>0$. By definition $$Vol(L)=\lim sup_{p\to\infty}\frac{n!}{p^n}dim H^0(X,L^p)$$ $\endgroup$
