Algebraic and Arithmetic Geometry Seminar: "A geometric proof of the classification of T-polygons."

Abstract: One formulation of mirror symmetry predicts (omitting a few adjectives) a one-to-one correspondence between equivalence classes of lattice polygons and deformation families of del Pezzo surfaces. Lattice polygons that correspond to smooth Del Pezzo surfaces are called T-polygons and have been classified by Kasprzyk-Nill-Prince using combinatorial methods, thereby verifying the conjecture in the smooth case. I will give a new geometric proof of their classification result.
