The Optional Sampling Theorem for Martingales Indexed by Directed Sets

open access: yesAnnals of Probability, 1980
A natural generalization of the optional sampling theorem for martingales is given. For discrete valued stopping times the result holds for directed sets; for more general stopping times the result holds for lattices satisfying a type of separability condition. The discrete case improves a lemma of Chow.

Doob’s optional sampling theorem in Riesz spaces

open access: yesPositivity, 2011
This paper is a continuation of the author's paper [Positivity 14, No. 4, 731--751 (2010; Zbl 1216.46005)] where the author defined continuous time stochastic processes in Riesz spaces and proved the Doob-Meyer decomposition theorem for martingales. In this paper the notions of stopping times and stopped processes for continuous stochastic processes ...

A CENTRAL LIMIT THEOREM FOR LATIN HYPERCUBE SAMPLING WITH DEPENDENCE AND APPLICATION TO EXOTIC BASKET OPTION PRICING [PDF]

open access: yesInternational Journal of Theoretical and Applied Finance, 2012
We consider the problem of estimating 𝔼[f(U1, …, Ud)], where (U1, …, Ud) denotes a random vector with uniformly distributed marginals. In general, Latin hypercube sampling (LHS) is a powerful tool for solving this kind of high-dimensional numerical integration problem. In the case of dependent components of the random vector (U1, …, Ud) one can achieve

Stopped processes and Doob's optional sampling theorem

open access: yes, 2020
Using the spectral measure $μ_\mathbb{S}$ of the stopping time $\mathbb{S},$ we define the stopping element $X_\mathbb{S}$ as a Daniell integral $\int X_t\,dμ_\mathbb{S}$ for an adapted stochastic process $(X_t)_{t\in J}$ that is a Daniell summable vector-valued function.

Beyond Wald's Equation and the Optional Sampling Theorem

open access: yes
This paper establishes a conservation identity for mean-zero martingales stopped by extended-valued stopping times. For any mean-zero martingale $\{M_n\}$ and any extended-valued stopping time $T$ satisfying $E|M_T|I(T<\infty)<\infty$, the quantity $L\equiv E[M_T I(T<\infty)]$ exists and equals $\lim_n E[-M_n I(T>n)]$, a limit which always ...

Doob's type optional sampling theorems and a central limit theorem for demimartingales with applications to associated sequences

open access: yes
This paper extends classical probabilistic results to the broader class of demimartingales and demisubmartingales. We establish variants of Doob's-type optional sampling theorem under minimal structural conditions on stopping times, relying on monotonicity properties of indicator functions.
