Milton1st ed. 2015.Cham :Springer International Publishing :Imprint: Springer,2015.1 online resource (122 p.)SpringerBriefs in Physics,2191-5423Description based upon print version of record.3-319-20127-1 Includes bibliographical references.Historical introduction -- Review of classical action principles -- Classical field theory - electrodynamics -- Quantum Action Principle -- Time-cycle or Schwinger-keldysh Formulation -- Relativistic Theory of Fields -- Nonrelativistic Source theory -- Concluding remarks.Starting from the earlier notions of stationary action principles, these tutorial notes shows how Schwinger’s Quantum Action Principle descended from Dirac’s formulation, which independently led Feynman to his path-integral formulation of quantum mechanics. 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.SpringerBriefs in Physics,2191-5423Quantum theoryPhysicsMathematical physicsQuantum Physicshttps://scigraph.springernature.com/ontologies/product-market-codes/P19080History and Philosophical Foundations of Physicshttps://scigraph.springernature.com/ontologies/product-market-codes/P29000Mathematical Applications in the Physical Scienceshttps://scigraph.springernature.com/ontologies/product-market-codes/M13120Mathematical Methods in Physicshttps://scigraph.springernature.com/ontologies/product-market-codes/P19013Quantum theory.Physics.Mathematical physics.Quantum Physics.History and Philosophical Foundations of Physics.Mathematical Applications in the Physical Sciences.Mathematical Methods in Physics.530.143Milton Kimball Aauthttp://id.loc.gov/vocabulary/relators/aut532655MiAaPQMiAaPQMiAaPQBOOK9910739419603321Schwinger's Quantum Action Principle1772332UNINA
