奇异辛结构的区别

Distinguishing between exotic symplectic structures

Richard M. Harris

摘要:

我们调查的唯一性,所谓的异国情调的结构,某些确切的辛流形,看看他们的辛性质的变化下小的非精确变形的辛形式。这使我们能够区分两个例子的基础上发现的\cite{maydanskiy,maydanskiyseidel},即使他们的经典辛不变量,如辛上同调消失。我们还展示,任何$n$,一个确切的辛流形与$n$独特的,但奇异的辛结构,这再次不能区分辛上同调。

英文摘要:

We investigate the uniqueness of so-called exotic structures on certain exact symplectic manifolds by looking at how their symplectic properties change under small nonexact deformations of the symplectic form. This allows us to distinguish between two examples based on those found in \cite{maydanskiy,maydanskiyseidel}, even though their classical symplectic invariants such as symplectic cohomology vanish. We also exhibit, for any $n$, an exact symplectic manifold with $n$ distinct but exotic symplectic structures, which again cannot be distinguished by symplectic cohomology.
