Vector fields on intrinsic mirrors

Mark Gross

(Cambridge)

Abstract

Siebert and I gave a general construction of mirror partners to log

Calabi-Yau pairs, we called these mirror partners "intrinsic mirrors". This talk

is about a small part of a larger project with Pomerleano and Siebert aimed

at understanding this construction at a deeper level. I will explain how to

construct vector fields on the mirror using enumerative geometry of the original

log Calabi-Yau pair.

Hurwitz-Brill-Noether Theory via K3 Surfaces

Sohelya Feyzbakhsh

(Imperial College London)

Abstract

I will discuss the Brill-Noether theory of a general elliptic $K 3$ $K 3$ surface using wall-crossing with respect to Bridgeland stability conditions. As an application, I will provide an example of a general $k$ -gonal curve from the perspective of Hurwitz-Brill-Noether theory. This is joint work with Gavril Farkas and Andrés Rojas.
