辛同胚的约化

Reduction of symplectic homeomorphisms

Vincent Humilière, Rémi Leclercq, Sobhan Seyfaddini

摘要:

在前一篇文章中,我们证明了保余迷向子流形C的辛同胚也保其特征叶理。因此,这种辛同胚下降到上各向同性C的约化。在这篇文章中,我们表明,这些减少同胚继续表现出一定的辛性质。特别是,在特定的设置,其中的辛流形是一个环面和上迷向是一个标准的子环面,我们证明了减少同胚保持谱不变量,从而谱容量。为了证明我们的主要结果,我们利用Lagrangian Floer理论构造了一类新的满足非标准三角不等式的谱不变量。

英文摘要:

In a previous article, we proved that symplectic homeomorphisms preserving a coisotropic submanifold C, preserve its characteristic foliation as well. As a consequence, such symplectic homeomorphisms descend to the reduction of the coisotropic C. In this article we show that these reduced homeomorphisms continue to exhibit certain symplectic properties. In particular, in the specific setting where the symplectic manifold is a torus and the coisotropic is a standard subtorus, we prove that the reduced homeomorphism preserves spectral invariants and hence the spectral capacity. To prove our main result, we use Lagrangian Floer theory to construct a new class of spectral invariants which satisfy a non-standard triangle inequality.
