  • Continuity of the Shafer-Vovk-Ville Operator
    arXiv: Probability, 2018
    Co-Authors: Natan T'joens, Gert De Cooman, Jasper De Bock
    Abstract:

    Kolmogorovs axiomatic framework is the best-known approach to describing probabilities and, due to its use of the Lebesgue integral, leads to remarkably strong continuity properties. However, it relies on the specification of a probability measure on all measurable events. The game-theoretic framework proposed by Shafer and Vovk does without this restriction. They define global upper expectation operators using local betting options. We study the continuity properties of these more general operators. We prove that they are continuous with respect to upward convergence and show that this is not the case for downward convergence. We also prove a version of Fatous Lemma in this more general context. Finally, we prove their continuity with respect to point-wise limits of two-sided cuts.
