WebDeﬁnition 1. Let (Ω,F,P) be a probability space. A ﬁltration on (Ω,F,P) is an increasing family (Ft)t≥0 of sub-σ-algebras of F. In other words, for each t, Ft is a σ-algebra included in F and if s ≤ t, Fs ⊂ Ft. A proba-bility space (Ω,F,P) endowed with a ﬁltration (Ft)t≥0 is called a ﬁltered probability space.
