 Title: Mirror Symmetry for Log CalabiYau Surfaces
 Abstract :
The SYZ conjecture asserts that for a CalabiYau manifold, the mirror pair should carry dual special Lagrangian torus fibrations. Extending beyond the CalabiYau case, to semiFano Log CalabiYau surfaces to be precise, one should consider what is known as the LandauGinzburg model, i.e. a Laurent polynomial defined on the mirror space (which is called the potential). Using new tropical geometric ideas, we give a closedstring version of the mirror symmetry for such semiFano Log CalabiYau surfaces, that is, we show isomorphism between the quantum cohomology of the surface and the Jacobian ideal ring of the potential.
