一个无限阶软木塞

An infinite order cork

Selman Akbulut

摘要:

我们构造了一个无限阶cork(W,f),这意味着W是一个具有Stein结构的光滑紧致可压缩4-流形,f是W的边界的自同构,使得n重合成映射f^{n}= fofo…o f对于足够大的n值产生光滑不同的软木塞(W,f^{n}),因为它接近无穷大。

英文摘要:

We construct an infinite order cork (W,f), which means that W is a smooth compact contractible 4-manifold with Stein structure, and f is a self diffeomorphism of the boundary of W, such that the n-fold composition maps f^{n}=f o f o... o f give rise to smoothly distinct corks (W, f^{n}) for sufficiently large values of n, as it approaches to infinity.
