Ai. Kirillov, GENERATING FUNCTIONALS OF S-MATRIX AND SCHWINGER-FUNCTIONS IN WN-ANALYSIS .1., Theoretical and mathematical physics, 111(1), 1997, pp. 395-404
It is shown that the generating functionals of S-matrix and Schwinger
functions are U-functionals of white noise analysis. This result is ap
plied to the regularization of the generating functionals.
