On the mirrors of low-degree del Pezzo surfaces
Giulia Gugiatti, Franco Rota
We compare different constructions of mirrors of del Pezzo surfaces, focusing on degree . In particular, we extract Lefschetz fibrations, with associated exceptional coll…

Hyperelliptic Integrals and Mirrors of the Johnson-Kollár del Pezzo Surfaces
Alessio Corti, Giulia Gugiatti
For all k>0 integer, we consider the regularised I-function of the family of del Pezzo surfaces of degree 8k+4 in P(2,2k+1,2k+1, 4k+1), first constructed by Johnson and Kollár. We…
