报告摘要: In this talk , we establish the quantitative mean ergodic theorems for two subclasses of power bounded operators on a fixed noncommutative Lp - space with 1< p < o ∞, which mainly concerns power bounded invertible operators and Lamperti contractions . Our approach to the quantitative ergodic theorems is the noncommutative square function inequalities . The establishment of the latter involves several new ingredients such as the almost orthogonality and Calderon - Zygmund arguments for non - smooth kernels from semi - commutative harmonic analysis , the extension properties of the operators under consideration from operator theory , and a noncommutative version of the classical transference method due to Coifman and Weiss .
