Abstract
In this paper, we suggest a representation for an inverse transform of the generalized Fourier-Feynman transform on the function space C<sub>a,b</sub>[0, T]. The function space C<sub>a,b</sub>[0, T] is induced by the generalized Brownian motion process with mean function a(t) and variance function b(t). To do this, we study the generalized Fourier-Feynman transform associated with the Gaussian process Ƶ<sub>k</sub> of exponential-type functionals. We then establish that a composition of the Ƶ<sub>k</sub>-generalized Fourier-Feynman transforms acts like an inverse generalized Fourier-Feynman transform.
