SPRINGERBRIEFS IN PHYSICS QUANTUM FIELD THEOR...

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.
