Green–Griffiths–Lang conjecture for compactified ball quotients

From papers

Let \overline{X} = \overline{{\left.\raisebox{-.2em}{\Gamma}\middle\backslash\raisebox{.2em}{\mathbb B^n}\right.}} be a compactification as in Theorem, with n6n \geq 6. Here DD denotes the boundary of X\overline{X}, and an entire curve means a holomorphic map from C\mathbb C to X\overline{X}. Green–Griffiths–Lang conjecture for compactified ball quotients. There exists an algebraic subset ΣX\Sigma \subset \overline{X} with

dimΣ5\dim \Sigma \leq 5

such that every non-constant entire curve, or every subvariety that is not of general type, is contained in DΣD \cup \Sigma. This is presented as a consequence of the Green–Griffiths–Lang conjecture in the setting of compactified ball quotients; the stated result uses the preceding theorem that subvarieties of dimension at least 66 outside the boundary are of general type. The general conjectural statement remains open.
