The Feynman integral [126] gives an intuitive picture of quantum mechanics as a classical mechanics with some quantum corrections describing interference of various classically inadmissible amplitudes. In addition to its intuitive appeal the Feynman integral can be considered as a useful calculational tool.

What follows is a continuation of the general theory developed in Chapter IV. This prolongation was more or less inspired by the excellent Paris These of Felix Pham. Briefly speaking it deals with the subgraphs, open or closed, of the basic graph G. The geometric methods of Chapter IV continue to prevail.

In these lectures I shall present a path integral calculation, starting from a global definition of Feynman path integrals and ending at a scattering cross section formula. Along the way I shall discuss some basic issues which had to be resolved to exploit the computational power of the proposed definition of Feynman integrals.

The present chapter is devoted to a rigorous treatment of the ’sums over paths’ proposed by Feynman as an alternative calculus for quantum mechanics. We begin with a formulation of the problem and a brief survey of some approaches to it. In Section 2 we study a theory in which the path integrals under consideration are defined by a Parseval-type ...

The aim of this chapter is to introduce the concept of the Feynman path integral. As well as developing the general construction scheme, particular emphasis is placed on establishing the interconnections between the quantum mechanical path integral, classical Hamiltonian mechanics, and classical statistical mechanics.

The following result confirms an hypothesis made in theoretical physics (see J. Lascoux and F. Pham [2]), whose main part was recently proved by D. Fotiadi [1], (namely the existence of the algebraic singular support).
