Abstract: The distance from the convex hull of the range of an $ n$-dimensional vector-valued measure to the range of that measure is no more than $ \alpha n/2$, where $ \alpha $ is the largest (one-dimensional) mass of the atoms of the measure. The case $ \alpha = 0$ yields Lyapounov's Convexity Theorem; applications are given to the bisection problem and to the bang-bang principle of optimal control theory.
