. The goal of this paper is to establish the Calabi-Yau/Landau-Ginzburg (CY/LG) correspondence for the tt ∗ geometry structure, which is thought to hold all genus 0 information about B-models. More explicitly, given a non-degenerate homogeneous polynomial f ∈ C [ z 1 , . . . , z n ] of degree n , one can investigate the Landau-Ginzburg B-model, which concerns the deformation of singularities. Its zero set, on the other hand, defines a Calabi-Yau hypersurface X f in P n − 1 , whereas the Calabi… 

Constructing the LG/CY isomorphism between $tt^*$ geometries

A bstract . For a nondegenerate homogeneous polynomial f ∈ C [ z 0 ,. .., z n + 1 ] with degree n + 2, we can obtain a tt ∗ structure from the Landau-Ginzburg model ( C n + 2 , f ) and a (new) tt ∗

N=2 LANDAU-GINZBURG VS. CALABI-YAU σ-MODELS: NON-PERTURBATIVE ASPECTS

We discuss some nonperturbative aspects of the correspondence between N=2 Landau-Ginzburg orbifolds and Calabi-Yau σ-models. We suggest that the correct framework is Deligne’s theory of mixed Hodge

THE LANDAU-GINZBURG/CALABI-YAU CORRESPONDENCE

More generally, the correspondence relates the FJRW theory of (W,G) to the Gromov-Witten theory of [XW/(G/〈J〉)] whenever a Calabi-Yau condition is satisfied. In this lecture, we will explain why such

Landau-Ginzburg/Calabi-Yau correspondence, global mirror symmetry and Orlov equivalence

We show that the Gromov-Witten theory of Calabi-Yau hypersurfaces matches, in genus zero and after an analytic continuation, the quantum singularity theory (FJRW theory) recently introduced by Fan,

tt* geometry, Frobenius manifolds, their connections, and the construction for singularities

The base space of a semiuniversal unfolding of a hypersurface singularity carries a rich geometry. By work of K. Saito and M. Saito is can be equipped with the structure of a Frobenius manifold. By

WITTEN DEFORMATION FOR NONCOMPACT MANIFOLDS WITH BOUNDED GEOMETRY

Motivated by the Landau–Ginzburg model, we study the Witten deformation on a noncompact manifold with bounded geometry, together with some tameness condition on the growth of the Morse function f

Kodaira-Spencer theory of gravity and exact results for quantum string amplitudes

We develop techniques to compute higher loop string amplitudes for twistedN=2 theories withĉ=3 (i.e. the critical case). An important ingredient is the discovery of an anomaly at every genus in

Primitive forms via polyvector fields

We develop a complex differential geometric approach to the theory of higher residues and primitive forms from the viewpoint of Kodaira-Spencer gauge theory, unifying the semi-infinite period maps
