Automorphisms of P1-bundles over rational surfaces

2023, Blanc, Jérémy, Andrea Fanelli, Ronan Terpereau

In this paper we provide the complete classification of $\mathbb{P}^1$-bundles over smooth projective rational surfaces whose neutral component of the automorphism group is maximal. Our results hold over any algebraically closed field of characteristic zero.
