SpringerBriefs in Physics Quantum Field Theory and Functional Integrals - Nima Moshayedi Kartoniert (TB)

Described here is Feynman's path integral approach to quantum mechanics and quantum field theory from a functional integral point of view. Therein lies the main focus of Euclidean field theory. The notion of Gaussian measure and the construction of the Wiener measure are covered. As well the notion of classical mechanics and the Schrödinger picture of quantum mechanics are recalled. There the equivalence to the path integral formalism is shown by deriving the quantum mechanical propagator from it. Additionally an introduction to elements of constructive quantum field theory is provided for readers.
