Abstract:

We discuss how invariants of Fano varieties can be read off from their Landau–Ginzburg models. We show how to get information about Hodge numbers and anticanonical linear system (in particular, we discuss Katzarkov–Kontsevich–Pantev conjectures). We also discuss how to get rationality and structure of derived category from singular fibers of Landau–Ginzburg models, and why one needs to consider their deformations.
