Strong Lang–Vojta conjecture for exceptional sets

About 6 years old · traced to

Let (X,D)(X,D) be a pair defined over a number field kk, where XX is a normal projective variety and DD is a normal crossing divisor. The pair is of log general type if, for a log resolution (Y,DY)(Y,D_Y), the divisor KY+DYK_Y+D_Y is big. An (S,D)(S,D)-integral point is a section of a model of (X,D)(X,D) over Spec⁡Ok\operatorname{Spec} \mathcal O_k whose pulled-back boundary is supported in SS.

Strong Lang–Vojta conjecture. The pair (X,D)(X,D) is of log general type if and only if there exists a proper closed subset

Z=Exc⁡(X,D),Z=\operatorname{Exc}(X,D),

called the exceptional set, such that X∖ZX\setminus Z has only finitely many (S′,D)(S',D)-integral points for every finite extension k′⊃kk'\supset k, where S′S' is the set of places above SS.

This conjecture predicts that the arithmetic of the complement of the exceptional set is finite precisely for pairs of log general type. It is presented as a fundamental conjecture governing rational and integral points, and the supplied text gives no resolution status.
