A measure-valued analogue of Wiener measure and the measure-valued Feynman-Kac formula

In this article, we consider a complex-valued and a measure-valued measure on , the space of all real-valued continuous functions on . Using these concepts, we establish the measure-valued Feynman-Kac formula and we prove that this formula satisfies a Volterra integral equation. The work here is patterned to some extent on earlier works by Kluvanek in 1983 and by Lapidus in 1987, but the present setting requires a number of new concepts and results.
