关于具有固定特征叶层的余迷向子流形的形变

On deformations of coisotropic submanifolds with fixed characteristic foliation

Stephane Geudens

AI总结:

本文研究辛流形中紧致余迷向子流形的形变问题,证明在固定特征叶层微分同胚类型的条件下形变无阻碍,从而推广了 Ruan 关于积分余迷向子流形的无阻碍性结果。

摘要:

众所周知,辛流形中紧致余迷向子流形 $C$ 的形变问题通常受到阻碍。我们证明,如果只允许其特征叶层与 $C$ 的特征叶层微分同胚的余迷向形变,则该问题变为无阻碍的。这推广了 Ruan 在积分余迷向子流形情形下得到的一个无阻碍性结果。

英文摘要:

It is well-known that the deformation problem of a compact coisotropic submanifold $C$ in a symplectic manifold is obstructed in general. We show that it becomes unobstructed if one only allows coisotropic deformations whose characteristic foliation is diffeomorphic to that of $C$. This extends an unobstructedness result in the setting of integral coisotropic submanifolds due to Ruan.
