Divonne's higher-order jet-differential ampleness conjecture
Divonne's higher-order jet-differential ampleness conjecture
Let be the intersection of at least very general hypersurfaces of sufficiently high degree. Let denote the bundle of invariant jet differentials of order and weighted degree .
Higher-order jet-differential ampleness conjecture. The bundle map
is ample, and therefore is hyperbolic.
This is proposed as a higher-order generalization of Debarre's cotangent-bundle ampleness conjecture, since . The source notes vanishing results for low jet order and explains that ampleness would imply Kobayashi hyperbolicity; the proposed generalization remains open.
