AI 中文总结
本文推广Hutchings的ECH方法，研究四维凸环面域及其并集的辛嵌入障碍，并利用交正性发现新障碍，阻碍嵌入间同伦的存在。
AI 中文摘要
在《超越ECH容量》中，Hutchings利用ECH协边映射为将一个凸环面域嵌入另一个凸环面域构造了障碍。我们将那里的方法推广，以阻碍不相交凸环面域并集到另一凸环面域的辛嵌入。我们还发现了来自交正性的额外障碍，并使用类似方法阻碍两个给定辛嵌入之间同伦的存在。
英文摘要
In Beyond ECH Capacities, Hutchings used the ECH cobordism map to produce obstructions for embedding one convex toric domain into another. We generalize the methods there to obstruct symplectic embeddings of a disjoint union of convex toric domains into another convex toric domain. We also find additional obstructions coming from intersection positivity and use similar methods to obstruct the existence of isotopies between two given symplectic embeddings.
