摘要
Some atomic decomposition theorems are proved in vector-valued weak martingale Hardy spaces w (p) Sigma(alpha)(X), w(p)Q(alpha)(X) and wD(alpha)(X). As applications of atomic decompositions, a sufficient condition for sublinear operators defined on some vector-valued weak martingale Hardy spaces to be bounded is given. In particular, some weak versions of martingale inequalities for the operators f*, S-(p)(f) and sigma((p))(f) are obtained.
