翻译后摘要:我们认为大规模的克莱因-戈登方程的渐近闵可夫斯基时空,在这个意义上说,流形是$\Bbb{R}^{1+d}$和度量的方法,闵可夫斯基空间在无穷远的短程方式,联合在时间和空间变量。在此设置中,我们定义了费曼和反费曼散射数据,并证明了Fredholm性质的Klein-Gordon算子与相关的广义Atiyah-Patodi-Singer型边界条件在无限次。然后我们构造了Fredholm问题的一个参数(带紧余项),并证明了它也是Duistermaat和H“Ormander意义下的Feynman参数.
Abstract:We consider the massive Klein-Gordon equation on asymptotically Minkowski spacetimes, in the sense that the manifold is $\Bbb{R}^{1+d}$ and the metric approaches that of Minkowski space at infinity in a short-range way, jointly in time and space variables. In this setup we define Feynman and anti-Feynman scattering data and prove the Fredholm property of the Klein-Gordon operator with the associated generalized Atiyah-Patodi-Singer type boundary conditions at infinite times. We then construct a parametrix (with compact remainder terms) for the Fredholm problem and prove that it is also a Feynman parametrix in the sense of Duistermaat and H\"ormander.
