报告摘要：In this talk, I shall present the joint work with Eric Ricard, which asserts that the almost uniform convergence may not happen for truly noncommutative Lp -martingales when p < 2. The same happens to ergodic averages. The proof consists of some sharp estimates of the distributional function of a sequence of matrices and some non standard transference techniques, which might admit further applications.
