Abstract

In order to study integral points of bounded log-anticanonical height on weak del Pezzo surfaces, we classify weak del Pezzo pairs. As a representative example, we consider a quartic del Pezzo surface of singularity type A1+A3\mathbf{A}_1+\mathbf{A}_3 and prove an analogue of Manin's conjecture for integral points with respect to its singularities and its lines.
