Debarre's ampleness conjecture for generic complete intersections
Let be an integer and let satisfy . For positive integers , choose generic hypersurfaces
with , and set
Debarre's ampleness conjecture. There is a positive lower bound , depending on and , such that whenever , the cotangent bundle is ample.
This conjecture extends Debarre's result for complete intersections in abelian varieties and concerns the expected positivity of cotangent bundles of sufficiently high-degree generic complete intersections in projective space. The paper presents a proof in the stated range, but the supplied parser status gives no explicit resolution evidence.
