Following the renewed interest in the topic [ Halliwell and Yearsley Phys. Field theory is always OK because classical fields are continuous. An alternative to the effective field theory approach to treat ghosts in higher derivative theories is to attempt to integrate them out via the Euclidean path integral formalism. (Other structures which are used to define quantum field theories, such as vertex operator algebras are now more or less understood to be special cases of these two approaches. 'He argues that from the path integrals approach to quantum field theory, Euclidean four dimensional space makes the most sense, and Unitary group U(2) is a proper subset of Special Orthogonal group SO(4). FIELD.THEORY.A.Path.Integral.Approach.pdf. Functorial quantum field theory: FQFT. D 86 024016 (2012)], we revisit the problem of assigning probabilities to classes of Feynman paths passing through specified space-time regions. World Scientific Lecture Notes in Physics - Vol. FIELD THEORY A Path Integral Approach. There are some indications that such higher categorical structures, such as those appearing in groupoidification, are essential for clarifying some of the mysteries of quantum field theory, such as the path integral.
