Part I brings out in more detail the connection between the two formulations, and applications are discussed. Then, the Keldysh-Schwinger time-cycle method of extracting matrix elements is described. Part II will discuss the variational formulation of quantum electrodynamics and the development of source theory. 410 0$aSpringerBriefs in Physics,$x2191-5423 606 $aQuantum theory 606 $aPhysics 606 $aMathematical physics 606 $aQuantum Physics$3https://scigraph.springernature.com/ontologies/product-market-codes/P19080 606 $aHistory and Philosophical Foundations of Physics$3https://scigraph.springernature.com/ontologies/product-market-codes/P29000 606 $aMathematical Applications in the Physical Sciences$3https://scigraph.springernature.com/ontologies/product-market-codes/M13120 606 $aMathematical Methods in Physics$3https://scigraph.springernature.com/ontologies/product-market-codes/P19013 615 0$aQuantum theory. 615 0$aPhysics. 615 0$aMathematical physics. 615 14$aQuantum Physics. 615 24$aHistory and Philosophical Foundations of Physics. 615 24$aMathematical Applications in the Physical Sciences. 615 24$aMathematical Methods in Physics. 676 $a530.143 700 $aMilton$b Kimball A$4aut$4http://id.loc.gov/vocabulary/relators/aut$0532655 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9910739419603321 996 $aSchwinger's Quantum Action Principle$91772332 997 $aUNINA
