Orbifold Green–Griffiths–Lang conjecture

Let X\mathcal{X} be an orbifold, and let ZX\mathcal{Z}\subset\mathcal{X} be a sub-orbifold. A holomorphic map f:CXf:{\mathbb C}\to\mathcal{X} is an orbifold entire curve.

Orbifold Green–Griffiths–Lang conjecture. If X\mathcal{X} is of general type, then there exists a proper sub-orbifold ZX\mathcal{Z}\subset\mathcal{X} containing the image of every holomorphic map f:CXf:{\mathbb C}\to\mathcal{X}.

This generalizes the Green–Griffiths–Lang conjecture from varieties to orbifolds. The paper presents it as a proposed generalization, and its general status is open.
