关于开书分解的Legendrian嵌入

On Legendrian Embbeddings into Open Book Decompositions

Selman Akbulut, M. Firat Arikan

摘要:

研究了紧致Legendrian子流形$L$在闭切触流形$(M,ξ)$中的Legendrian嵌入,该闭切触流形的切触结构由$M$上的(切触)开书$\mathcal{OB}$支持.我们证明了,如果$\mathcal{OB}$有Weinstein页,那么存在一个切触结构$ξ'$ $M$,同位素$ξ$和$\mathcal{OB}$支持,和接触同构$f:(M,ξ) \to (M,ξ')$,使任何这样的子流形的图像$f(L)$可以勒让德同位素,使它成为不相交的一页的封闭$\mathcal{OB}$。

英文摘要:

We study Legendrian embeddings of a compact Legendrian submanifold $L$ sitting in a closed contact manifold $(M,ξ)$ whose contact structure is supported by a (contact) open book $\mathcal{OB}$ on $M$. We prove that if $\mathcal{OB}$ has Weinstein pages, then there exist a contact structure $ξ'$ on $M$, isotopic to $ξ$ and supported by $\mathcal{OB}$, and a contactomorphism $f:(M,ξ) \to (M,ξ')$ such that the image $f(L)$ of any such submanifold can be Legendrian isotoped so that it becomes disjoint from the closure of a page of $\mathcal{OB}$.
