本文主要研究Stein流形的辛拓扑。如果我们有一个辛流形,如果存在一个复结构J和一个穷举(即真的,从下有界的)多重次调和函数W,那么我们说它具有Stein结构!就是这样!D dd,其中d由D.A/.X/WD da.jx/定义。三重流形称为斯坦流形。我们称Stein流形是有限类型的,如果只有有限多个临界点,每个临界点都是非退化的。
This paper is about the symplectic topology of Stein manifolds. If we have a symplectic manifold .V; !/, then we say it carries a Stein structure if there exists a complex structure J and an exhausting (ie proper and bounded from below) plurisubharmonic function W V ! R such that ! D dd , where d is defined by d.a/.X / WD da.JX /. The triple .V;J; / is called a Stein manifold. We say that a Stein manifold is of finite type if only has finitely many critical points, each of which is nondegenerate.
