Horospherical 2-Fano varieties

Abstract

We classify $2$-Fano horospherical varieties with Picard number $1$. We also review all the known examples of $2$-Fano manifolds and investigate the relation between the $2$-Fano condition and different notions of stability. This paper was conceived as a contribution to the Edge Volume: 2018-2022.
