基于Feynman和Hibbs的思想,给出了Feynman路径积分中泛函导数的严格数学定义。在这个定义中,属于藤原类的泛函可以被区分多次。此外,泰勒展开式和分部积分对泛函导数也成立。
Based on Feynman and Hibbs’s idea, we give a mathematically rigorous definition of functional derivatives in Feynman path integral. In this definition, the functionals which belong to Fujiwara’s class, can be differentiated as many times as we want. Furthermore, the Taylor expansion formula and the integration by parts hold with respect to the functional derivatives.
