| Abstract: | Weak atomic decompositions of B-valued martingales with two-parameters in weak Hardy spaces w p Σα and w p H α are established and the boundedness of sublinear operators on these spaces are proved. By using them, some characterizations of the smoothness of Banach spaces are obtained. |
