Let $$\pi :V\rightarrow M$$ be a (real or holomorphic) vector bundle whose base has an almost Frobenius structure $$(\circ _{M},e_{M},g_{M})$$ and typical fiber has the structure of a Frobenius algebra $$(\circ _{V},e_{V},g_{V})$$. Using a connection $$D$$ on the bundle $$\pi : V{\,\rightarrow \,}M$$ and a morphism $$\alpha :V\rightarrow TM$$, we construct an almost Frobenius structure $$(\circ , e_{V},g)$$ on the manifold $$V$$ and we study when it is Frobenius. In particular, we describe all… 



Weak Frobenius manifolds

We establish a new universal relation between the Lie bracket and $\circ$-multiplication of tangent fields on any Frobenius (super)manifold. We use this identity in order to introduce the notion of

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

On the structure of Brieskorn lattices, II

We give a simple proof of the uniqueness of extensions of good sections for formal Brieskorn lattices, which can be used in a paper of C. Li, S. Li, and K. Saito for the proof of convergence in the

Period Mapping Associated to a Primitive Form

The aim of this note is to give a summary of the study of primitive forms and period mappings associated with a universal unfolding F of an isolated hypersurface singularity, which was studied in
