introduction to continuous time filters

... time with respect to the filtration (Ft Gt )t∈I Given a stochastic process and a stopping time we can define a new stochastic process by stopping the old one In case the stopping time is finite, we ... stochastic process The case where I = N corresponds to stochastic processes in discrete time ( see Probability Theory, chapter 19 ) Since this section is devoted to stochastic processes in continuous ... stopping time : Definition 1.2.2 A stopping time with respect to a filtration (Ft )t∈I is an F measurable random variable τ : Ω → I ∪ {∞} such that for all t ∈ I we have τ −1 (It ) ∈ Ft A stopping time...
