DESCRIPTION:Title: <a href="https://researchseminars.org/talk/notts_ag/90/
 ">A geometric proof of the classification of T-polygons</a>\nby Wendelin L
 utz (Imperial) as part of Online Nottingham algebraic geometry seminar\n\n
 \nAbstract\nOne formulation of mirror symmetry predicts (omitting a few ad
 jectives) a one-to-one correspondence between equivalence classes of latti
 ce polygons and deformation families of del Pezzo surfaces. Lattice polygo
 ns 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 ge
 ometric proof of their classification result.\n
