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…

Full exceptional collections for anticanonical log del Pezzo surfaces
Giulia Gugiatti, Franco Rota
Motivated by homological mirror symmetry, this paper constructs explicit full exceptional collections for the canonical stacks associated with the series of log del Pezzo surfaces…

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…
