Yang-Mills连接和Einstein度规的指数能量估计

Index-energy estimates for Yang-Mills connections and Einstein metrics

Matthew J. Gursky, Casey Lynn Kelleher, Jeffrey Streets

摘要:

本文证明了作用于四维流形上向量丛的薛定谔算子的指数的一个共形不变估计,该估计与经典的Cwikel-Lieb-Rozenblum估计有关.应用到杨-米尔斯连接,我们得到了它的能量是共形不变的,并捕获急剧增长率的指数的约束。此外,我们得到了一个指数估计的爱因斯坦度量的拓扑结构和Einstein-Hilbert能量。最后,我们得到了具有正数量曲率的定向四维流形的贝蒂数的共形不变估计。

英文摘要:

We prove a conformally invariant estimate for the index of Schrödinger operators acting on vector bundles over four-manifolds, related to the classical Cwikel-Lieb-Rozenblum estimate. Applied to Yang-Mills connections we obtain a bound for the index in terms of its energy which is conformally invariant, and captures the sharp growth rate. Furthermore we derive an index estimate for Einstein metrics in terms of the topology and the Einstein-Hilbert energy. Lastly we derive conformally invariant estimates for the Betti numbers of an oriented four-manifold with positive scalar curvature.
