Figure 1From: Optimal resource allocation in wireless communication and networkingNonatomic measure. The random variable X is uniformly distributed in[0,1]∪[2,3]. The measure w X (E):=2 ∫ E xdX is nonatomic because all sets of nonzero probability include a smaller set of nonzero probability. Lyapunov’s convexity theorem (Theorem 2) states that the measure rangeW:={ w X (E):E∈B} is convex. The range of w X is the, indeed convex, interval [0,3].Back to article page
