A mathematical theory of the Feynman path integral for the generalized Pauli equations. (English) Zbl 1125.81034

The present paper,based on the works of C. Groche and F. Steiner [Handbook of Feynman path integrals. Berlin: Springer (1998; Zbl 1029.81045)] and of L. S. Schulman [Techniques and applications of path integration. New York etc.: John Wiley & Sons, Inc. (1981; Zbl 0587.28010)], introduces the Feynman path integral and the phase space Feynman path integral for the generalized Pauli equation. The Feynman path integral is developed from the time-slicing method through broken line paths by considering the stability of Feynman functional integrals over infinitely differentiable functions in \(\mathbb R^n\) by means of the theory of oscillatory integral operators referring to a precedent publication of the author [cf. J. Math. Soc. Japan 55, 957–983 (2003; Zbl 1053.81063)]
