大上同调类中多重次调和上包络的正则性

Regularity of plurisubharmonic upper envelopes in big cohomology classes

Robert Berman, Jean-Pierre Demailly

摘要:

本文的目的是证明某些拟多重次调和上包络的正则性。在紧致复流形上的大线丛上构造具有最小奇点的厄米特度量时,这种包络以一种自然的方式出现。我们证明了这些包络的复Hessian形式在奇点的解析集外是局部有界的。它进一步表明,这个结果的参数化版本产生一个先验不等式的解决方案的狄利克雷问题退化的Monge-Ampere算子;应用测地线的空间中的Kahler度量进行了讨论。类似的技术为Tsuji的“超正则”度量提供了一个对数连续模,它推广了Narasimhan-Simha的一个著名结构。

英文摘要:

The goal of this work is to prove the regularity of certain quasi-plurisubharmonic upper envelopes. Such envelopes appear in a natural way in the construction of hermitian metrics with minimal singularities on a big line bundle over a compact complex manifold. We prove that the complex Hessian forms of these envelopes are locally bounded outside an analytic set of singularities. It is furthermore shown that a parametrized version of this result yields a priori inequalities for the solution of the Dirichlet problem for a degenerate Monge-Ampere operator; applications to geodesics in the space of Kahler metrics are discussed. A similar technique provides a logarithmic modulus of continuity for Tsuji's "supercanonical" metrics, which generalize a well-known construction of Narasimhan-Simha.
