Unfoldings of Meromorphic Connections and a Construction of Frobenius Manifolds
نویسنده
چکیده
The existence of universal unfoldings of certain germs of meromorphic connections is established. This is used to prove a general construction theorem for Frobenius manifolds. It includes semisimple Frobenius manifolds as a particular case. Another special case starts with variations of Hodge structures. This case is used to compare two constructions of Frobenius manifolds, the one in singularity theory and the Barannikov– Kontsevich construction. For homogeneous polynomials which give Calabi– Yau hypersurfaces certain Frobenius submanifolds in both constructions are isomorphic.

Riemann-Hilbert problem associated to Frobenius manifold structures on Hurwitz spaces: irregular singularity
Solutions to the Riemann-Hilbert problems with irregular singularities naturally associated to semisimple Frobenius manifold structures on Hurwitz spaces (moduli spaces of meromorphic functions on Riemann surfaces) are constructed. The solutions are given in terms of meromorphic bidifferentials defined on the underlying Riemann surface. The relationship between different classes of Frobenius ma...
متن کاملGeometry , 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 it can be equipped with the structure of a Frobenius manifold. By work of Cecotti and Vafa it can be equipped with tt∗ geometry if the singularity is quasihomogeneous. tt∗ geometry generalizes the notion of variation of Hodge structures. In the second part of this ...

متن کاملUniversal unfoldings of Laurent polynomials and tt∗ structures
This article surveys the relations between harmonic Higgs bundles and Saito structures which lead to tt geometry on Frobenius manifolds. We give the main lines of the proof of the existence of a canonical tt structure on the base space of the universal unfolding of convenient and nondegenerate Laurent polynomials.
متن کاملOn Almost Duality for Frobenius Manifolds
We present a universal construction of almost duality for Frobenius manifolds. The analytic setup of this construction is described in details for the case of semisimple Frobenius manifolds. We illustrate the general considerations by examples from the singularity theory, mirror symmetry, the theory of Coxeter groups and Shephard groups, from the Seiberg Witten duality.
