在之前的文章中,作者介绍了封闭定向三流形的不变量,使用黎曼曲面对称积中拉格朗日弗洛尔同调的变体进行定义。本文的目的是介绍使用这些 Floer 同调群构建的定向、平滑四流形的不变量。这种四维理论还赋予相应的三维理论额外的结构:某些弗洛尔同调群的绝对分级。
In earlier articles, the authors introduced invariants for closed, oriented three-manifolds, defined using a variant of Lagrangian Floer homology in the symmetric products of Riemann surfaces. The aim of this article is to introduce invariants of oriented, smooth four-manifolds, built using these Floer homology groups. This four-dimensional theory also endows the corresponding three-dimensional theories with additional structure: an absolute grading of certain of its Floer homology groups.
