One of the most useful results from Malliavin malluavin is the Clark-Ocone theoremwhich allows the process in the martingale representation theorem to be identified explicitly.
A similar idea can be applied in stochastic analysis for the differentiation along a Cameron-Martin-Girsanov direction. All articles with unsourced statements Articles with unsourced statements from August Articles lacking in-text citations from June All articles lacking in-text citations.
Malliavin calculus is also called the stochastic calculus of variations.
The existence of this adjoint follows from the Riesz representation theorem for linear operators on Hilbert spaces. The calculus has applications for example in stochastic filtering.
June Learn how and when to remove this template message. His calculus enabled Malliavin to prove regularity bounds for the solution’s density. From Wikipedia, the free encyclopedia.

In particular, it allows the computation of derivatives of random variables. Retrieved from ” https: Please help to improve this article by introducing more precise citations.
In probability theory and related fields, Malliavin calculus is a set of malliavni techniques and ideas that extend the mathematical field of calculus of variations from deterministic functions to stochastic processes. The calculus allows integration by parts with random variables ; this operation is used in mathematical finance to compute the sensitivities of financial derivatives.

A simplified version of this theorem is as follows:. Views Read Edit View history.
calucl The calculus has applications in, for example, stochastic filtering. The calculus has been applied to stochastic partial differential equations as well. The calculus has been applied to stochastic partial differential equations.
