The Feynman Integrand for the Perturbed Harmonic Oscillator as a Hida Distribution

2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/57309We review some basic notions and results of White Noise Analysis that are used in the construction of the Feynman integrand as a generalized White Noise functional. We show that the Feynman integrand for the harmonic oscillator in an external potential is a Hida distribution.Mathematical Physics60H40; 81S40, 58D30, 46T12The Feynman Integrand for the Perturbed Harmonic Oscillator as a Hida Distributiontext
