  • Beschreibung: <p>Convergence properties are obtained for repeated applications of the operator f → |f - E(f)|, where E denotes conditional expectation. If, for example, E is the integral with respect to a probability measure P, f ∈ L<sup>∞</sup>(P) and T(f) = |f - E(f)|, then T<sup>n</sup>(f) converges to 0 in L<sup>∞</sup>(P) and Σ T<sup>n</sup>(f) converges in L<sup>1</sup>(P).</p>
