I'm trying to prove the following: >Let $L$ be a positive holomorphic line bundle on a compact complex manifold $X$. For any hermitian holomorphic vector bundle $E$ on $X$, there is $k \in \mathbb{N}$ such that $E\otimes L^k$ is Nakano positive. I'm using the decomposition given by diverietti in <a href="http://mathoverflow.net/a/133376/21564">this answer</a>. Part of my problem is that (I think) I can find a sufficiently large choice of $k$ so that $E\otimes L^k$ is Nakano positive at a point, but I can't extend beyond that. If I try to prove that I can find such a $k$ locally, my bounds are no longer valid. Maybe I need to use the fact that $X$ is locally compact. >Does anyone have a reference (or proof) of the above fact? --- **Update:** I'm not actually sure that the statement I'm trying to prove is true, though I feel like it should be.
