The Bichteler-Dellacherie Theorem | Almost Sure
https://almostsure.wordpress.com/2011/03/28/the-bichteler-dellacherie-theorem
Filed under: Stochastic Calculus Notes. The General Theory of Semimartingales. 8212; George Lowther @ 12:30 PM. In this post, I will give a statement and proof of the Bichteler-Dellacherie theorem describing the space of semimartingales. A semimartingale, as defined in these notes. Is a cadlag adapted stochastic process X. Such that the stochastic integral. Is well-defined for all bounded predictable. And satisfies bounded convergence in the following sense. If. In probability as n. For a fixed time t.

Filtrations and Adapted Processes. Filed under: Filtrations and Processes. 8212; George Lowther @ 12:22 AM. In the previous post I started by introducing the concept of a stochastic process, and their modifications. It is necessary to introduce a further concept, to represent the information available at each time. A. On a probability space. Is a collection of sub-sigma-algebras of. The idea is that. Represents the set of events observable by time. The probability space taken together with the filtration.
Cadlag Modifications | Almost Sure
https://almostsure.wordpress.com/2009/12/18/cadlag-modifications
Filed under: Filtrations and Processes. 8212; George Lowther @ 1:46 AM. As was mentioned in the initial post of these stochastic calculus notes, it is important to choose good versions of stochastic processes. In some cases, such as with Brownian motion, it is possible to explicitly construct the process to be continuous. However, in many more cases, it is necessary to appeal to more general results to assure the existence of such modifications. The left limit at any time. The jump at time. If and only i...
Quasimartingales | Almost Sure
https://almostsure.wordpress.com/2012/04/12/quasimartingales
Filed under: Stochastic Calculus Notes. The General Theory of Semimartingales. 8212; George Lowther @ 12:30 PM. Are a natural generalization of martingales, submartingales and supermartingales. They were first introduced by Fisk in order to extend the Doob-Meyer decomposition. To a larger class of processes, showing that continuous quasimartingales can be decomposed into martingale and finite variation terms ( Quasi-martingales. Often, given a process, it is important to show that it is a semimartingale.
The Doob-Meyer Decomposition | Almost Sure
https://almostsure.wordpress.com/2011/12/30/the-doob-meyer-decomposition
Filed under: Stochastic Calculus Notes. The General Theory of Semimartingales. 8212; George Lowther @ 12:30 PM. The Doob-Meyer decomposition was a very important result, historically, in the development of stochastic calculus. This theorem states that every cadlag submartingale. Uniquely decomposes as the sum of a local martingale. And an increasing predictable process. For one thing, if X. Is a square-integrable martingale then Jensen’s inequality. Is a local martingale. The term. Using a stochastic int...

Well, not her literally but just one of those women who have everything under control like work and home. It’s been a struggle for me for far too long and I’ve decided with the help of my good friend the internet that I can find ways that’ll work for me. But, with a minor inspection of my dishwasher I’m not so sure the filter at the bottom comes off. So who really knows if I’l...

Rao’s Quasimartingale Decomposition. Filed under: Stochastic Calculus Notes. The General Theory of Semimartingales. 8212; George Lowther @ 12:30 PM. In this post I’ll give a proof of Rao’s decomposition for quasimartingales. That is, every quasimartingale decomposes as the sum of a submartingale and a supermartingale. Equivalently, every quasimartingale is a difference of two submartingales, or alternatively, of two supermartingales. This was originally proven by Rao ( Quasi-martingales. Rao’s deco...

Almost Surreptitious | This blog is about me.
This blog is about me. May 9, 2010. Posted by almost0surreptitious under Uncategorized. I stopped seeing animals as tools. Now I am starting to see them as people. This will change me far beyond the changes to a vegan lifestyle. If animals are people, people can’t be held to the standards of conformity and norms that I have internalized or invented in my human life. People have to be listened to in a way that goes far beyond words or self-interest with a short grace period extended to others. May 4, 2010.
