DESCRIPTION:Speakers: Hülya Argüz (Oxford)\n\nIn joint work with Pierric
 k Bousseau\, we established a correspondence between two seemingly differe
 nt kinds of sheaf and curve counting invariants. On the sheaf theoretic si
 de are the Vafa–Witten invariants of the projective plane\, which arise 
 from gauge theory\, and on the other side are curve-counting invariants gi
 ven by logarithmic Gromov–Witten theory of the mirror to the projective 
 plane. I will describe this correspondence and show how it can be used to 
 explain predicted mock modular behavior in the generating functions of log
 arithmic Gromov–Witten invariants. This is based on recent work: https:
