From the Peierls bracket to the Feynman functional integral
The paper consists of two parts written by the first and the second author, respectively. In the first part the functional integration is defined via the Peierls bracket and Schwinger's variational principle. In the second part the basic properties of functional integration, used in the definition and evaluation of Feynman functional integrals, are presented. The authors say that this is the first contact point between their contributions to functional integration.
