Title:Mirror symmetry of Fano toric $A$-model and Landau-Ginzburg $B$-model
Seminar:GAP Seminar
Speaker:Yong-Geun Oh, University of Wisconsin - Madison
In this talk, I will introduce the notions of weakly unobstructed Lagrangian submanifolds and balanced Lagrangian submanifolds. I will explain construction of certain potential function constructed out of study of deformation theory of Floer cohomology and explain its relationship to the earlier work of Givental which advocates that quantum cohomology ring is isomorphic to the Jacobian ring of Landau-Ginzburg superpotential. I will explain these results in the context of mirror symmetry between Fano toric A-model and Landau-Ginzburg B-model. This is a joint work with Fukaya, Ohta and Ono.
