WebAug 31, 2024 · Theorem (Debut theorem) Let X be an adapted right-continuous stochastic process defined on a complete filtered probability space. τ ( ω) = inf { t ∈ R +: X t ( ω) ≥ K } is a stopping time. A process X stopped at the random time τ is denoted by X τ X t τ ( ω) = X t ∧ τ ( ω) ( ω).

WebThe Début theorem says that the hitting time of a measurable set F, for a progressively measurable process, is a stopping time. Progressively measurable processes include, in particular, all right and left-continuous adapted processes . The proof that the début is measurable is rather involved and involves properties of analytic sets. WebKeywords: Stopping time, hitting time, progressively measurable, optional, predictable, debut theorem, section theorem Abstract Under very general conditions the hitting time of a set by a stochastic process is a stopping time. We give a new simple proof of this fact. The section theorems for optional and predictable sets are
