Transforms and convolutions on function space

Seung Jun Chang and Jae Gil Choi

Dankook University

Abstract

In this paper, for functionals of a generalized Brownian motion process, we show that the generalized Fourier-Feynman transform of the convolution product is a product of multiple transforms and that the conditional generalized Fourier-Feynman transform of the conditional convolution product is a product of multiple conditional transforms. This allows us to compute the (conditional) transform of the (conditional) convolution product without computing the (conditional) convolution product.

Keywords: generalized Brownian motion process, generalized Fourier-Feynman transform, convolution product, conditional generalized Fourier-Feynman transform, conditional convolution product
