Full characterizations of the variational McShane Integral on $m$-dimensional compact intervals (1611.03331v2)

Abstract: In this paper we consider the additive interval functions defined on the family $\mathcal{I}{m}$ of all non-degenerate closed subintervals of the cubic interval $C{m} = [0,1]^{m}$ in the $m$-dimensional Euclidean space $\mathbb{R}^{m}$ and taking values in a Banach space $X$. We give necessary and sufficient conditions for an additive interval function $F : \mathcal{I}{m} \to X$ to be the primitive of a variational McShane (or strong McShane) integrable function $f : C{m} \to X$ in terms of the convex cubic average range of $F$.
