摘要: X是可分自反Banach空间,{Ft,Ft,tR+}是取值于X中闭凸集的可测集值随机过程.该文证明了,若任给停时T,FTI[T<∞]关于Ft(相应地关于Ft-)是σ-可积,则{Ft,tR+}必存在可选(相应地可料)投影过程.

Abstract: Let {Ft,Ft,tR+} be a measurable multivalued stochas processes valued in a seperable reflexive Banach Space. The preset paper shows that if for every stopping time T,FTI[T<∞] is σ-integrable with respect to the σ -field of events(strictly) prior to T, Then {Ft,tR+) has an opitional (predictable) projection processe.
