【摘要】 本文给出平方可积轶x∈βμθ，平方可积强鞅x∈βμθs的几个充要条件，在g（F4）条件下，过程x在停点z处的停止xz，过程x的连续部分xc保存即βμθ性质，得到了几个βμθs范数不等式。更多还原

【Abstract】 <Abstrart> This paper gives several ample conditions of ∈βμθ of square integrablemartingales and x∈βμθ of square integrable strong martingales,winder g(F4) condition,Stopping x2 at the stopping point Z,the continuous part xc of process x keeps the βμθ feature,and several norm inequalities of βμθ are obtained.更多还原
