A simplified version of this theorem is as follows:. The calculus has been applied to stochastic partial differential equations as well.
The calculus has applications for example in stochastic filtering.
Malliavin calculus – Wikipedia
From Wikipedia, the free encyclopedia. One of the most useful results from Malliavin calculus is the Clark-Ocone theoremwhich allows the process in the martingale representation theorem to be identified explicitly.

The calculus allows integration by parts with random variables ; this operation is used in mathematical finance to compute the sensitivities of financial derivatives. In particular, it allows the computation of derivatives of random variables.
Please help to improve this article by introducing more precise citations. A similar idea can be applied in stochastic analysis for the differentiation along a Cameron-Martin-Girsanov direction.
Retrieved from ” https: This article includes a list of referencesrelated reading or external linksbut its sources remain unclear because it lacks inline citations. The calculus has been applied to stochastic partial differential mwlliavin.
The existence of this adjoint follows from the Riesz representation theorem for linear operators on Hilbert spaces. In probability theory and related fields, Malliavin calculus is a set of mathematical techniques and ideas that caocul the mathematical field of calculus of variations from deterministic functions to stochastic processes.
The calculus has applications in, for example, stochastic filtering. His calculus enabled Malliavin to prove regularity bounds for the solution’s density. Views Read Edit View history.
