Outline of Final Research Achievements |
We investigated some characterizations of a Banach function space X such that various martingale inequalities remain valid in the weak space w-X. A Banach function space is a function space which is a generalization of the well-known Lp-space, and the weak space of a Banach function space X is a quasi-Banach space associated with X, which is a generalization of the weak-Lp-space. As a result of our investigations, we could give characterizations of Banach function space X such that martingale inequalities such as of Burkholder-type and of Doob-type, and so on remain valid in w-X, and we could show that there is close connection between martingale theory and the structures of (quasi-)Banach function spaces.
