 Abstract
Let C[0, t] denote a generalized Wiener space, the space of real-valued continuous functions on the interval [0, t] and define a random vector by , where 0 < < < < t is a partition of [0, t] and with a.e. In this paper we will introduce a simple formula for a generalized conditional Wiener integral on C[0, t] with the conditioning function and then evaluate the generalized analytic conditional Wiener and Feynman integrals of the cylinder function for , where and e is a unit element in . Finally we express the generalized analytic conditional Feynman integral of F as two kinds of limits of non-conditional generalized Wiener integrals of polygonal functions and of cylinder functions using a change of scale transformation for which a normal density is the kernel. The choice of a complete orthonormal subset of used in the transformation is independent of e and the conditioning function does not contain the present positions of the generalized Wiener paths.
