线性化作用的等变体积
Equivariant volumes for linearized actions
摘要:
设给定极化复射影流形(M,L)上的线性化作用,并假定稳定轨迹非空。研究了L的高次幂的整体瓣空间中的等变和项的维数的首渐近性。我们使用Kirwan决议和一个基本的代数几何参数,以减少问题的情况下,非奇异的行动(即,行动的稳定和半稳定的轨迹重合,是非空的)。
英文摘要:
Suppose given a linearized action on a polarized complex projective manifold (M,L), and assume that the stable locus is non-empty. We study the leading asymptotics of the dimension of the equivariant summands appearing in the space of global sections of high powers of L. We use Kirwan resolutions and an elementary algebro-geometric argument to reduce the problem to the case of non-singular actions (that is, actions for which the stable and semistable loci coincide and are non-empty).
