DESCRIPTION:Let S be a toric del Pezzo surface and let E be a smooth antic
 anonical divisor on it. In this talk\, I consider both the log geometry gi
 ven by the pair (S\,E) and the local geometry given by the total space of 
 O(-E). The claim is that for the purpose of genus 0 mirror symmetry\, they
  form equivalent geometries. The genus 0 A-model invariants are related to
  each other by a version of open-closed duality and the B-model geometries
  by the double suspension. After describing the relevant constructions\, I
  will formulate a theorem of relative mirror symmetry in this context.
