Abstract: In this talk we will talk about our recent results about the Picard group of generic (very general) Vafa-Witten spectral varieties. We will first review the concept of spectral varieties, Higgs sheaves and their relation with the Noether-Lefschetz type Theorems. Then we introduce our main results and an application.
