Descriptive characterisation of the variational Henstock-Kurzweil-Stieltjes integral and applications

We derive a descriptive characterisation of the vector-valued variational Henstock-Kurzweil-Stieltjes integral extending and improving previous results. We also give several applications of our characterisation, e.g., to the recover of a function from a relative derivative, the characterisation of Banach spaces with the Radon-Nikodým property and to the study of certain normed algebras of differentiable functions on compact plane sets.
