Apr 7, 2020 at 9:47 comment added Ben McKay Real line bundles don't admit a complex structure, for example the trivial real line bundle.

Apr 7, 2020 at 5:41 comment added abx Complex line bundles on a manifold $X$ are classified by the first Chern class $c_1\in H^2(X,\mathbb{Z})$. If $X$ is a compact Kähler manifold, such a line bundle is holomorphic if and only if $c_1$ is of type $(1,1)$.
Apr 6, 2020 at 21:44 comment added Andy Sanders Nadia, if you are interested in real vector bundles that don't admit the structure of a complex vector bundle, then you should say so. Because, while not trivial, this can be investigated by methods of algebraic topology. Meanwhile, since you use the word holomorphic in your title, you should specify that you are interested in complex vector bundles, since otherwise it's not clear what you are interested in. I think you might have stumbled into a very deep question on accident.

Apr 5, 2020 at 12:44 comment added Nadia SUSY @Thomas: So what are interesting examples of bundles that do not admit almost complex structures?
