The authors consider random variables defined on a Wiener space, and with values in a manifold or in the tangent bundle of this manifold. They define the stochastic differentiation for such variables in a way which extends the case of real-valued variables. Then, by considering the adjoint of this differentiation operator, they construct the Skorokhod integral of a process which is tangent to some random time-independent point of the manifold. Finally, a formula which gives the covariance of two Skorokhod integrals and which involves the curvature of the manifold is proved.
