报告摘要：In this talk, I shall present our recent result on the mapping properties of a square function from ergodic theory on noncommutative Lp-spaces. The main result is a weak (1,1) type estimate of this noncommutative square function.We also show (L∞,BMO) estimate, and obtain strong (Lp, Lp) estimate by interpolation. The main difficulty lies at the fact that the kernel of this square function does not enjoy any regularity, which will be overcome by the almost orthogonality principle and some delicate analysis of the kernel.
