Equidistribution and the torsor method

Christian Bernert, Ulrich Derenthal, Florian Wilsch

We prove equidistribution and Manin's conjecture for rational points outside the lines on smooth split quintic del Pezzo surfaces over number fields with respect to any anticanonic…

Integral points over number fields: a Clemens complex jigsaw puzzle

Christian Bernert, Ulrich Derenthal, Judith Ortmann +1

We prove an asymptotic formula for the number of integral points of bounded log anticanonical height on a singular quartic del Pezzo surface over arbitrary number fields, with resp…

Iitaka fibrations and integral points: a family of arbitrarily polarized spherical threefolds

Ulrich Derenthal, Florian Wilsch

Studying Manin's program for a family of spherical log Fano threefolds, we determine the asymptotic number of integral points whose height associated with an arbitrary ample line b…

Integral points of bounded height on quintic del Pezzo surfaces over number fields

Christian Bernert, Ulrich Derenthal

We prove an asymptotic formula for the number of integral points of bounded log-anticanonical height on split smooth quintic del Pezzo surfaces over number fields, with respect to…

Points of bounded height on quintic del Pezzo surfaces over the rational numbers

Christian Bernert, Ulrich Derenthal

We give a relatively short and elementary proof of Manin's conjecture for split smooth quintic del Pezzo surfaces over the rational numbers.

Manin's conjecture for the chordal cubic fourfold

Ulrich Derenthal

We prove the thin set version of Manin's conjecture for the chordal (or: determinantal) cubic fourfold, which is the secant variety of the Veronese surface. We reduce this counting…
