Abstract. Using Nonstandard Analysis, we will provide a rigorous computation for the harmonic oscillator Feynman path integral. The computation will be done without having prior knowledge of the classical path. We will see that properties of classical physics falls out naturally from a purely quantum mechanical point of view. We will assume that the reader is familiar with Nonstandard Analysis. I. Introduction. In quantum mechanics, we are interested in finding the wave function which satisfies Schrodinger’s equation. Equivalently, we can find the propagator or integral kernel K(q, q0, t) which satisfies

Abstract. We derive a functional integral representation for the partition function of a We are developing a set of tools and techniques for analyzing the large distance/infrared behaviour of a system of identical bosons, as the temperature tends to zero. The total energy of the many boson systems considered in this paper has two sources. First, each particle in the system has a kinetic energy. We shall denote the corresponding
