The Feynman integrand for the perturbed harmonic oscillator as a Hida distribution


  • Research Center Bielefeld-Bochum-Stochastik.


We 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.
