Vojta's conjecture with multiplier ideal sheaves

Let X\mathcal X be a smooth projective variety defined over Q\mathbb Q, with canonical divisor KXK_\mathcal X, ample divisor A\mathcal A, and nonzero ideal sheaf I\mathcal I. Let SS be a finite set of places of Q\mathbb Q containing MQM_\mathbb Q^\infty. Write I\mathcal I^- for the associated limiting multiplier ideal sheaf, and let hKXh_{K_\mathcal X}, hAh_\mathcal A, λI\lambda_\mathcal I, and λI\lambda_{\mathcal I^-} denote the corresponding height functions.

Vojta's multiplier-ideal conjecture. For every real ε>0\varepsilon>0 and positive integer rr, there is a proper Zariski-closed subset ZXZ\subsetneq\mathcal X, depending only on X,I,A,ε,r\mathcal X,\mathcal I,\mathcal A,\varepsilon,r, such that

hKX(x)+νSλI(x,ν)νSλI(x,ν)εhA(x)+d(x)+O(1),h_{K_\mathcal X}(\mathbf x)+\sum_{\nu\in S}\lambda_\mathcal I(\mathbf x,\nu)-\sum_{\nu\in S}\lambda_{\mathcal I^-}(\mathbf x,\nu)\leq\varepsilon h_\mathcal A(\mathbf x)+d(\mathbf x)+O(1),

for all x(XZ)(Q)\mathbf x\in(\mathcal X\setminus Z)(\overline{\mathbb Q}) with [Q(x):Q]r[\mathbb Q(\mathbf x):\mathbb Q]\leq r.

This is a multiplier-ideal formulation of Vojta's conjecture, replacing normal-crossings data by a correction term. Its general status is open.
