"Journal of Mathematical Physics" [Em linha]. ISSN 0022-2488. Vol. 46, nº 6 (May 2005), p. 1-140022-2488Art. No. 063505http://hdl.handle.net/10400.2/1679The Feynman integral for the Schrödinger propagator is constructed as a generalized function of white noise, for a linear space of potentials spanned by finite signed measures of bounded support and Laplace transforms of such measures, i.e., locally singular as well as rapidly growing at infinity. Remarkably, all these propagators admit a perturbation expansion.engFeynman integralsWhite noise analysisjournal article
