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. .SpringerBriefs in Physics,2191-5431Quantum physicsFunctional analysisQuantum PhysicsFunctional AnalysisQuantum physics.Functional analysis.Quantum Physics.Functional Analysis.530.143Moshayedi Nima1253162MiAaPQMiAaPQMiAaPQBOOK9910734880403321Quantum Field Theory and Functional Integrals3403489UNINA
