Let $X$ be a projective manifold. The anticanonical bundle is nef when $-K_X$ has nonnegative degree on every curve. The Albanese map is the canonical morphism from $X$ to its Alba…

Let $X$ be a projective manifold, let $L$ be a numerically trivial line bundle, and let $v \in H^0(X,\bigwedge^q T_X \otimes L)$ be a non-trivial section. A zero of $v$ is a point…
