In mirror symmetry, there is a symplecto-geometric A-side geometry and a complex algebro-geometric B-side geometry. To each side is associated its A- resp B-variation problem. Enumerative Mirror Symmetry is the prediction of equivalence of variation problem, resulting in a calculation scheme to compute the Gromov-Witten invariants of the A-side. In joint work with Ruddat and Siebert, in the setting of log del Pezzo surfaces, we prove that enumerative mirror symmetry is a consequence of the Gross-Siebert Intrinsic Mirror Construction. I will describe this work in the case of the projective plane.
Prof. van Garrel is a researcher in algebraic geometry and mirror symmetry. He specialises in enumerative geometry, in particular log Gromov-Witten theory, in birational geometry, especially with regard to rationality questions and in the Gross-Siebert programme as the mechanism that explains mirror symmetry and constructs mirror families.
