Abstract

Our goal of this note is to give an easy proof that spaces of predictable processes with values in a Banach space are isomorphic to spaces of progressive resp. adapted, measurable processes. This provides a straightforward extension of the Itô integral in infinite dimensions. We also outline an application to stochastic partial differential equations.
