论文摘要
我们构建了一个软木塞的示例，该示例在使用$ s^2 \ times s^2 $的连接总和后保持异国情调。结合了Akbulut-Ruberman的作品，这意味着存在异国情调的一对可缩度的4个Manifolds，在使用$ S^2 \ times s^2 $的连接总和后，它们仍然绝对异国情调。
We construct an example of a cork that remains exotic after taking a connected sum with $S^2 \times S^2$. Combined with a work of Akbulut-Ruberman, this implies the existence of an exotic pair of contractible 4-manifolds which remains absolutely exotic after taking a connected sum with $S^2 \times S^2$.
