概要 | We study certain degenerate abelian schemes that are GIT-stable in the sense that their SL-orbits are closed in the semistable locus. We prove the vanishing of the cohomology groups H^q(Q,L^n) for q,n >0 for a naturally defined ample invertible sheaf L on Q. When n=1, this implies that H^0(Q,L), the space of global sections, is an irreducible module of the noncommutative Heisenberg group of (Q,L). |
