Equivariant pliability of the projective space (2202.09319v1)
Published 18 Feb 2022 in math.AG
Abstract: We classify finite subgroups $G\subset\mathrm{PGL}_4(\mathbb{C})$ such that $\mathbb{P}3$ is not $G$-birational to conic bundles and del Pezzo fibrations, and explicitly describe all $G$-Mori fibre spaces that are $G$-birational to $\mathbb{P}3$ for these subgroups.
