WebQuantum Field Theory and the Path Integral 5.1 Preliminaries We will consider the case of a classical scalar ﬁeld theory and its quantization. Later in this book we will consider both vector and spinor ﬁelds. A classical scalar ﬁeld φ(xμ)is a real-valued function of the coordinates of space and time. One common approach to deriving the path integral formula is to divide the time interval into small pieces. Once this is done, the Trotter product formula tells us that the noncommutativity of the kinetic and potential energy operators can be ignored.
