Mirror fibrations and root stacks of weighted projective spaces
Ignacio de Gregorio, Etienne Mann
We show that the orbifold Chow ring of a root stack over a well-formed weighted projective space can be naturally seen as the Jacobian algebra of a function on a singular variety g…

Some examples of non-massive Frobenius manifolds in Singularity Theory
Ignacio de Gregorio
Let $f,g:\cc^2\ra\cc$ be two quasi-homogeneous polynomials. We compute the -filtration of the restriction of to any plane curve and show that the Gorenstein…

Deformations of functions and F-manifolds
Ignacio de Gregorio
We study functions on isolated singularities and prove some results of type Milnor number = Tjurina number. We use them to endow the base space of their miniversal deformation with…
