量子电动力学中的高阶估计
On higher order estimates in quantum electrodynamics
摘要：
本文提出了一种新的方法来推导量子电动力学中的某些高阶估计。我们的方法是特别方便的应用到非局域半相对论量子电动力学模型，因为它避免了使用迭代换位子展开。我们重新推导高阶估计较早获得的Fröhlich，Griesemer，和Schlein和证明新的估计的非本地分子不对运营商。
英文摘要：
We propose a new method to derive certain higher order estimates in quantum electrodynamics. Our method is particularly convenient in the application to the non-local semi-relativistic models of quantum electrodynamics as it avoids the use of iterated commutator expansions. We re-derive higher order estimates obtained earlier by Fröhlich, Griesemer, and Schlein and prove new estimates for a non-local molecular no-pair operator.
