渐近Minkowski时空II上的大质量Feynman传播子
The massive Feynman propagator on asymptotically Minkowski spacetimes II
摘要:
本文考虑短程渐近Minkowski时空上的大质量Klein-Gordon方程。推广了文[GW 1]中的结果,证明了具有Feynman型边界条件的Klein-Gordon算子在无穷次是可逆的,其逆算子(称为Feynman逆)满足Duistermaat和Hörmander意义下的Feynman参数的微局部条件.这补充了最近的工作Vasy更明确的技术。
英文摘要:
We consider the massive Klein-Gordon equation on short-range asymptotically Minkowski spacetimes. Extending our results in [GW1], we show that the Klein-Gordon operator with Feynman type boundary conditions at infinite times is invertible and that its inverse, called the Feynman inverse, satisfies the microlocal conditions of Feynman parametrices in the sense of Duistermaat and Hörmander. This supplements the recent work of Vasy with more explicit techniques.
