Ampleness conjecture for jet differential bundles on generic complete intersections

From papers

Let XPNX\subset \mathbb{P}^N be a generic complete intersection variety of dimension nn and codimension cc. For integers kk and mm as in the jet-differential construction, let Ek,mΩXE_{k,m}\Omega_X denote the corresponding jet differential bundle. Jet-differential ampleness conjecture. If knck\geqslant \lceil\frac{n}{c}\rceil, then Ek,mΩXE_{k,m}\Omega_X is ample. This is presented as a stronger conjectural positivity statement related to Debarre's conjecture on ample cotangent bundles. The surrounding discussion notes that the paper proves numerical positivity and bigness results as evidence, but does not establish this ampleness assertion.
