一次稳定化对可缩4维流形而言是不够的
One stabilization is not enough for contractible 4-manifolds
AI总结:
该研究构造了与$S^2 \ imes S^2$取连通和后仍具异质性的cork例子,结合已有工作证明存在取该连通和后仍保持绝对异质性的可缩4维流形异质对,推进了4维流形稳定化相关研究。
摘要:
我们构造了一个软木(cork)的例子,它在与$S^2 \times S^2$取连通和后仍保持异质性。结合Akbulut-Ruberman的一项工作,这意味着存在一对可缩4维流形的异质对,它们在与$S^2 \times S^2$取连通和后仍保持绝对异质性。
英文摘要:
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 $S^2 \times S^2$.
