摘要

我们用白噪声演算给出了紧化爱因斯坦宇宙上费曼积分的严格构造。我们对函数平均的构造也可以被认为是对Bogoliubov和Shirkov提出的问题的解决方案。

Feynman integral in QFT and white noise on a compactified version of space–time with a Lie group structure

We present a rigorous construction of the Feynman integral on the compactified Einstein Universe using white noise calculus. Our construction of functional averaging can also be thought of as a solution to a problem posed by Bogoliubov and Shirkov.
