The converse from Kollár-hyperbolicity to V-hyperbolicity
The converse from Kollár-hyperbolicity to V-hyperbolicity
Let be a normal projective variety and let be a closed normal subgroup. Say that is Kollár-hyperbolic with respect to when the corresponding Kollár-hyperbolicity condition holds, and say that is V-hyperbolic with respect to when has infinite index and, for every -tower , every perverse sheaf underlying a mixed Hodge module, and every ,
Converse conjecture. If is Kollár-hyperbolic with respect to , then is V-hyperbolic with respect to .
The preceding lemma proves the converse implication from V-hyperbolicity to Kollár-hyperbolicity, so this conjecture asserts an equivalence. The paper says that supporting evidence is given in subsequent sections; no resolution is stated.
