A tt* viewpoint of Landau-Ginzburg models in various dimensions
I will introduce the Landau-Ginzburg models in two dimensions and present the higher dimensional cases as their generalizations. Then, we will analyze the UV and IR limits through tt* viewpoint and we will contrast it with the Picard-Lefschetz theory in these contexts. Then finally we will comment on the connection of the tt* geometry and the associated Hitchin system for the 2d case.
