Flat meromorphic connections of Frobenius manifolds with tt*-structure
Jiezhu Lin, Claude Sabbah
The base space of a semi-universal unfolding of a hypersurface singularity carries a rich geometric structure, which was axiomatized as a CDV-structure by C. Hertling. For any CDV-…

Some Constraints on Frobenius Manifolds with a TT*-Structure
Jiezhu Lin
The article gives a necessary and sufficient condition for a Frobenius manifold to be a CDV-structure. We show that there exists a positive definite CDV-structure on any semi-simpl…
