bounded FT-measurable) random variable. Stopping times A random variable ˝, valued in [0;1] is an F-stopping time if, for any t 0, f˝ tg 2 Ft.

A stopping time ˝is predictable if there exists an increasing sequence (˝n) of stopping times such that almost surely (i) limn˝n= ˝, (ii) ˝nset. Azéma associated with an honest time L the supermartingale and established some of its important properties. This supermartingale plays a central role in the general theory of stochastic processes and in particular in the theory of progressive enlargements of filtrations.

In this paper, we shall give an additive characterization for these supermartingales, which in turn will naturally provide. eBook Shop: Random Times and Enlargements of Filtrations in a Brownian Setting Lecture Notes in Mathematics von Roger Mansuy als Download.

() Let F t = Ïƒ(B s, 0 â‰¤ s â‰¤ t) denote the filtration generated by the Brownian motion B up to time instant t. Assume that G t is the enlargement of the filtration F t by knowing the random variables X 1, ÂÂÂ, X n at time t 1.

Enlargement of Filtration ([1] ) If G is a ltration larger than F, it is not true that an F-martingale is a G-martingale. K It o [3] was the rst to look at problems of enlargement of ltrations. From the seventies, Barlow, Jeulin and Yor started a systematic study of the problem of enlargement of ltrations.

This paper constructs a nonlinear filtering framework that admits appearances of new information processes at random times by introducing piecewise enlargements of filtrations and proposes a new energy-based Schrodinger evolution expressed as a stochastic differential equation on a complex Hilbert space.

Each information process is modeled as the sum of a random variable taking the eigenvalues. [50] R. M a n s u y, M. Y o r: Random times and (enlargement of filtrations) in a Brownian setting, Lecture Notes in Mathematics,Springer ().

In this note, using techniques of progressive enlargement of filtrations, we prove two theorems for the special, but important, cases when ρ is a pseudo-stopping time (Nikeghbali and Yor, ) or the end of a predictable set.

At an abstract level, this set-up can be considered an example of grossissement—the enlargement of filtrations. This theory was developed from the late s on, starting with the works of Barlow [6], Jeulin & Yor [25], [26], [27], and further developed by others including Yoeurp [35], and by Itô’s extension of the stochastic integral.Lecture Notes in Mathematics (共册), 这套丛书还有 《Topological Complexity of Smooth Random Functions》,《Random Times and Enlargements of Filtrations in a Brownian Setting (Lecture Notes in Mathematics)》,《Conference on Group Theory》,《Representation Theory II.

The most studied family of random times, after stopping times, are ends of optional sets, also named honest times (such the last zero of the standard Brownian motion before a fixed time). A very powerful, but not so well known, technique for studying such random times is that of the progressive expansions or enlargements of filtrations.
