本文研究了弱Orlicz鞅空间的双争不等式.利用鞅的极大箅子理论和弱Orliez范数的特点,得到了弱Orlicz鞅空间极大算子的Doob不等式和强弱(Ф1,Ф2)-型不等式.
In the paper, we study two Ф-inequalities in weak Orlicz martingale spaces. According to the theory of maximal operator for martingales and the characteristic of weak Orlicz norm, we obtain the Doob' s inequality and strong and weak (Ф1,Ф2 )-type inequalities on maximal operator.
