构造奇异辛四流形对,其拓扑不变量相同但辛小平维数不同,因辛小平维数在Luttinger手术下不变,从而否定Auroux的唯一性问题。
AI 中文摘要
我们构造了形成奇异对的单连通积分辛四流形,其$c_1^2$、$c_2$、$c_1\mathbin{\cdot}[\omega]$和$[\omega]^2$的值相等,但辛小平维数分别为$-\infty$和$2$。由于辛小平维数在Luttinger手术下不变,这两个流形不是Luttinger手术等价的。这对Auroux的唯一性问题给出了否定答案。
英文摘要
We construct simply connected integral symplectic four-manifolds forming an exotic pair, with equal values of $c_1^2$, $c_2$, $c_1\mathbin{\cdot}[ω]$, and $[ω]^2$, but with symplectic Kodaira dimensions $-\infty$ and $2$. Since symplectic Kodaira dimension is invariant under Luttinger surgery, the two manifolds are not Luttinger-surgery equivalent. This gives a negative answer to Auroux's uniqueness question.
