Generic nefness conjecture for the cotangent and tangent bundles

From papers

Let XX be a compact Kähler manifold, and let α1,,αn1\alpha_1,\ldots,\alpha_{n-1} be Kähler classes. For a coherent sheaf, generically nef means generically nef with respect to the indicated product of Kähler classes. Generic nefness conjecture. (1) If KXK_X is nef, then ΩX\Omega_X is α1αn1\alpha_1\cdots\alpha_{n-1}-generically nef. (2) If KX-K_X is nef, then TXT_X is α1αn1\alpha_1\cdots\alpha_{n-1}-generically nef. The conjecture is affirmatively solved in the projective case, but remains open for compact Kähler manifolds; the source attributes the difficulty to the lack of the required foliation theory in that setting.
