| Abstract: |
| In this paper we discuss the Rosenthal type inequality of quasi-martingale. By using good λ inequality, we prove that Rosenthal type inequality of quasi-martingale and geometric properties of Banach space are equivalent. As a consequence, we prove the law of large numbers. These conclusions generalize some known results. |
