Applications of white noise calculus to the computation of Feynman integrals
The paper is essentially based on the white noise calculus, developed by \textit{T. Hida} [Brownian motion (1980; Zbl 0432.60002)]. Lévy's stochastic area, considered in terms of Hida's calculus, is used to explicitly calculate the Feynman propagator in a uniform magnetic field. With the same technique, a rigorous treatment of Feynman integrals of two-time quadratic actions is given.
