Titre | Fukaya categories of Landau-Ginzburg models and functoriality in homological mirror symmetry |
Résumé | The main protagonist of this talk is the Fukaya category of a (type A) "Landau-Ginzburg model", i.e., a symplectic fibration over the complex plane. We will outline one definition of this category, and describe a pair of natural functors relating it to the Fukaya category of the fiber. These functors are of particular interest in homological mirror symmetry, where they correspond to inclusion and restriction functors between derived categories of coherent sheaves on a variety and a hypersurface inside it. This leads in particular to a proof of homological mirror symmetry for general hypersurfaces in toric varieties. The talk will be mostly expository; the non-expository parts are joint work with Mohammed Abouzaid on one hand, and the thesis work of Maxim Jeffs on the other hand. |
