Birational induction of nilpotent orbit covers in exceptional types (2312.01838v1)
Published 4 Dec 2023 in math.AG and math.RA
Abstract: Let $G$ be a semisimple simply connected algebraic group over ${\mathbb C}$ of exceptional type. For each $G$-equivariant nilpotent cover of a nilpotent coadjoint $G$-orbit ${\mathbb O}$, we determine the unique birationally rigid induction datum from which it is birationally induced.
