The conjecture on zeros of twisted multivector fields

Let XX be a projective manifold, let LL be a numerically trivial line bundle, and let vH0(X,qTXL)v \in H^0(X,\bigwedge^q T_X \otimes L) be a non-trivial section. A zero of vv is a point where its value vanishes. The zero-free multivector-field conjecture. If vv has a zero, then XX is uniruled. The assertion is clear when q=dimXq=\dim X, and the case q=1q=1 with LL trivial is classical; the general statement remains open in the source.
