In this paper atomic decompositions for two-parameter vector-valued martingales are given. With the help of the atomic decompositions
the relations between the mutual embedding of two-parameter vector-valued martingale spaces and geometric properties of Banach
spaces are investigated. Our study shows that geometric properties of Banach spaces determine the embedding of martingale
spaces and conversely the latter can characterize the former.

In this paper we define some weak martingale Hardy spaces and three kinds of weak atoms. They are the counterparts of martingale Hardy spaces and atoms in the classical martingale Hp-theory. And then three atomic decomposition theorems for martingales in weak martingale Hardy spaces are proved. With the help of the weak atomic decompositions of martingale, a sufficient condition for a sublinear operator defined on the weak martingale Hardy spaces to be bounded is given. Using the sufficient condition, we obtain a series of martingale inequalities with respect to the weak Lp-norm, the inequalities of weak (p ,p)-type and some continuous imbedding relationships between various weak martingale Hardy spaces. These inequalities are the weak versions of the basic inequalities in the classical martingale Hp-theory. 相似文献

Several theorems for atomic decompositions of Banach-space-valued martingales are proved. As their applications, the relationship
among some martingale spaces such asH
α(X) andρ
H
α in the case 0< α⩽ are studied. It is shown that there is a close connection between the results and the smoothness and convexity
of the value spaces.

Some atomic decomposition theorems for Banach-space-valued martingales are established. Using them, the embedding relationships
between martingale spaces with small index are discussed. The results obtained here are connected closely with thep-uniform smoothness and q-uniform convexity of Banach space in which the martingales take values. 相似文献
