Seiberg-Witten方程、周期尾Dirac算子和Rohlin不变量的提升

Seiberg-Witten equations, end-periodic Dirac operators, and a lift of Rohlin's invariant

Tomasz S. Mrowka, Daniel Ruberman, Nikolai Saveliev

摘要:

我们引入了具有$S^1 \times S^3$同调的光滑4-流形X的Rohlin不变量的规范论整数提升。不变量有两项;一个是X上Seiberg-Witten方程的解的计数,另一个本质上是Dirac算子在非紧流形上的指数,该流形的端点是X的无限循环覆盖.每个术语是度量(和扰动)依赖,我们表明,这些依赖关系取消的度量和扰动在1参数家庭的变化。

英文摘要:

We introduce a gauge-theoretic integer lift of the Rohlin invariant of a smooth 4-manifold X with the homology of $S^1 \times S^3$. The invariant has two terms; one is a count of solutions to the Seiberg-Witten equations on X, and the other is essentially the index of the Dirac operator on a non-compact manifold with end modeled on the infinite cyclic cover of X. Each term is metric (and perturbation) dependent, and we show that these dependencies cancel as the metric and perturbation vary in a 1-parameter family.
